TM Not showing any matches and previously translated units in Trados Studio 2021

Hello,

For some reason, my TM stopped showing me any matches in mid-project. The Lookup box is checked and the Look ahead feature too. I closed and restarted Trados, but to no avail. 

Also, all the units containing amounts of money are not being translated properly. For example, in French, we use commas in 9,999. Instead, Trados gives me 9999. Sometimes, the M$ is properly spaced, other times, not. There's a lot of discrepancies and since there's a lot of units containing amounts, the translation is time consuming and tedious.

I am using Trados Studio 2021 SR2.

Thank you for your help.
