This might be because the Auto-substutution setting:

it should be OK…

Could you please delete target of segment 22 and try confirming again segment 21? It may be a setting of Auto-Propagation that doesn’t propagate to already confirmed segments. To propagate to already confirmed segments, you need this check box ticked in Options > Editor > Auto-propagation:

If still doesn’t work, could you please check that GB is a measurement in the TM used? I’ve checked that GB is there by default for both English US and Norwegian, but it may have been deleted…

I believe it’s one of these 2 causes. Let us know the result of your tests.

I have the exact same settings and GB is in both languages. I deleted the target of segment 22 and confrimed segment 21. Same result. The space is missing in segment 22.

I've been seeing this issue for quite a few years. I have just installed the latest version of Studio and the issue is still there.

André Stryger ,

Sorry to hear that and I can’t think of anything else...

It works for me (segment #3 auto-propagated to segment #4 in Trados Studio 2022, 17.1.8.17828):

Segment 4 needs to have different numbers for this to be the same situation. Could you try that please?

Yep, it works too:

I even tried with your long original source text:

I used a different translation memory and then it worked. So I exported everything from the original memory and imported it into a new, empty memory. This one works too. However it is strange that the old memory was able to cause this issue.

Could you please check if the old TM recognises Measurements or not?
