Jerzy Czopik it looks to me as though this is because the result is coming from your TM and has nothing to do with the autosubstitution settings. I’d hazard a guess that if you had a recognised date in your TM for this match then the autosubstitution would work.

Interesting it’s a match repair though. What was repaired?

Paul I'd suppose the problem here is indeed the tag pair around the day part of the date. This has most probably prevented Studio from recognizing this as a complete date. And thus the repair.But I certainly do not have this date format in the TM. The suggested repaired segment was previously translated with the tag pair around the day, but with the same date. So what is inserting a wrong date here seems to be the match repair function. Would you like the files for checking? I can give you the complete project including the TM, if you want.

Yes please.  No rush as I'm on leave at the moment, but I would like to take a look.
