Hi everyone,

This is about a TM issue I have working with Trados Studio 2021. My company has been collecting TUs in a master TM for some time now and there are supposed to be about 160000 TUs inside. There actually have been until recently, we do not know when exactly this happened: all but the last 3243 TUs are somehow missing from the TM. 

The sdltm file seems large enough (698.232 KB) but upon opening the TM in Translation Memories view, the number of the first TU shown is 156076 and the settings show 3243 translation units. Exporting the TM to tmx creates a small file (3.387 KB). Translating a document from a few years ago (prepared in a project with this master TM) returns zero hits when there should be 100 % matches from this TM.

I have already tried the following:

• running the TM through SDLTM Repair > this showed no issues
• renaming TranslationMemoryRepository > this did not help
• saving the TM from a shared disk to a local disk > did not help
• I did not find any locked/hidden/protected TUs
• turning it off and on again

Because this is a very frustrating issue and an important TM for our everyday work, I would be truly grateful for any insights or additional suggestions: what could the issue be and how else can I try to solve it?

Thank you!
