I use Studio 2021 with  latest update. Furthermore, relevant Termbases are loaded from Multiterm (also latest version). A few days ago, known terms from the TM were dependably marked with the red marks. All of a sudden, this only takes place at times now. I did the reset (renaming Studio16 to Studio16 old, etc., everything to no avail). I even uninstalled both Studio 2021 and Multiterm 2021, to no avail. The associated TM works fine and displays sentences already translated. Some of them have the red marks, and the window (top right) shows the associated terms from the TB. But - as I said - not all terms although contained in the TB. I did the check by highlighting the terms to be entered in the TB, and then got the message that this term has already been entered. No red mark to be seen! What is wrong?
