Is my TM updating or not?

Question

Good day, I'm new here, having just purchased Trados. I have a few questions, starting with this one.(Thanks to Paul for his advice on posting.) 
 A TM viewed in the "Translation Memories" persistently shows no change since the update on 4 Dec even though I have tried numerous times to update it, including by realigning and importing from Alignment, and by redoing the translation. 
 
 However, in the Translation Memories folder it duly shows as modified today, 6 Dec, and when I reopen the original to check it by "translating" it again, I get 100% matches from an apparently updated TM. 
 
 None of the segments from this document appear in the Sv-En TM open in the Translation Memories window, in screenshot 1 above. 
 These are the Project Settings (nothing under All Language Pairs). 
 
 Should I even expect the TM view to show the updated TM? If not, I won't worry. 
 In general I confess I find the TM settings mysterious and overcomplicated. Considering they are the raison d'&ecirc;tre of the software, I would have preferred them to be simpler to set up. Why, for example, is this TM is listed under Swedish-English and not under All Language Pairs (i.e., what did I do to make that happen?!)? What is the difference between Project TMs and Main TMs, about which a dialog box pops up, asking me for some sort of choice when updating? 
 Any thoughts? 
 Thanks and regards 
 Nigel

 Thanks for posting with this detail... it does help to come up with some ideas. 
 First of all... you do know that the TM Maintenance View is only a maintenance view and it works on a page by page basis. So you will only ever see the first page... and however many TUs you have this set for. So try navigating to the end: 
 
 Apologies if that is a silly idea for you... 
 Another idea would be check whether you are using a Project TM or not. If you are then your Main T will not be updated until you either Finalize the project or run the Update Main TM batch task. But looking at your project settings you don't seem to be doing this.

 Nigel Lindup said: What does the warning "You have set up..." etc., at the bottom of the "All language pairs > Translation memories" view mean?

Then, in the "Swedish-English > Translation memories" view, what does "Use different translation providers.." mean? When I uncheck it, the box fills with a message "From All Language Pairs".

These are all related. They are all because you added your TM at the specific language pair here: 
 
 As opposed to at the All Language Pairs level here: 
 
 Adding at All Language Pairs carries advantages if you work with multilingual projects as you can apply the same settings for all language pairs as opposed to having to change the settings for each individual language pair you work with. If you only work with a single language pair it makes little difference... other than adding a little complexity for the majority of users who don't work with multilingual projects. 
 So you get this message on the All Language Pair level because you added your TM to the specific language pair: 
 
 You get this because if it was unchecked you would be drawing settings from the All Language Pairs: 
 
 For example: 
 
 Make sense?
