When you work as freelance and use EITHER the possibility to add TMs within the "All Language Pairs" part of the project creation wizard OR within the specific language pair there, you do not need to bother with this message. Please remember, that adding TMs in both location renders the complete project unworkable. Therefore, add the TMs either in this or in that other location, but NEVER in both.

You do not need to change anything within FIle -> Options, this will be done by Studio. But only if you work with single file approach. When you do this, you will find all the language pairs used with the single file approach within File -> Options. In case you really want to work that way (I would never recommend that, working with project templates is a much better way), you can modify the settings for each language pair listed under File -> Options that way, that the TMs for the very specific language pair are added there in the position "Specific language pair" (for example "English-German -> Translation memory and ...") instead of adding them under "All language pairs". This way, when you select the language pair at the start of a single file translation approach, only the TMs for the corresponding language pair will appear.

Thanks, Jerzy - and my apologies for not being able to spell such simple words as "the" in my intro! So I am a freelancer and have projects for each customer. if I have understood correctly, I should only be adding TMs in the specific German-English level and not under All language pairs? Does that mean if I remove any TMs in All language pairs in the project settings, this should solve the issue? I imagine I should also not use 2017 project templates for the 2021 projects?

In each project, I had included one TM under All language pairs. I just tried deleting the TM, checking on the TMs in the German-English setting, and clicking OK. But oddly even with no TM now und All language pairs, I still get the same message when I open Project Settings, All language pairs, Translation memories.

Not quite. You can safely keep the TMs in "All language pairs", for our usage it does not matter. It start matter, when you have multilingual projects, where it is simply a crawled view and hard to configure, if you put all the necessary TMs under All language pairs.

The message you're getting is no error, just a warning. However, please check, if you do not have activated this in your language pair:

If your settings look like mine, all is OK.

However, please note, that ALL project related changes MUST be done within the project settings and NEVER via File -> Options.

Thanks for that very clear answer! I'll check the settings - and then I'll stop worriyng.
