Trados 2017 auto-propagation doesn't work properly

Question

I have been using Trados 2015 freelance and upgraded to 2017 a few days ago, and I really regretted it. I didn't know I should not have deactivated 2015 before upgrading to 2017; this is not reversible and SDL refused to let me "downgrade" to 2015, but this is another story. Here I have a bigger issue. I was working on a file with approx. 4K segments, with supposedly many 100% and CMs which could be auto-propagated in 2015, i.e. I only had to work on first occurrences and Trados could deal with the 100%/repetitions. However, 2017 didn't auto-propagate those; instead, the match values were below 100% and I had to confirm every single segment, which was really time-consuming. Here's the comparison:

 I have made sure all the settings are identical in the global options and project settings of both Trados 2015 and 2017. Can anyone help please? Many thanks.

Hi Peggy Lin This looks like a TM setting, perhaps make sure that your TM is set to recognise alphanumerics? Go to TM Settings -> Fields and Settings and ensure everything is checked as you expect.

Hello Peggy Lin 
 
Please send me your TM and the original source file so I can investigate this. 
 
You can send it to pfilkin@sdl.com

Hi Peggy Lin 
 This is surely related to your autopropagation settings in File -> Options. I have cleared your translations in Studio 2017, confirmed the first segment and then see this without pressing another key:

Hi Peggy Lin 
 I was thinking about your situation a little so I took your source file out of the projects you sent me and tranlsated it again from scratch with a new TM in Studio 2015, 2017 and 2019 to see if I could at least reproduce what you have posted. I think the TMs you sent me didn't help because they were already populated which is why I had the result I did. 
 This time I get these: 
 
 So I can reproduce the problem you are having in 2017, and I've also verified it's been fixed in 2019 which is good. I don't believe there is a workaround to this problem in 2017 as it is going to require a fix from development. I'll drop you an email on what we do to help you here.
