Term recognition not working in Trados Studio 2021

Dear All,

I have recently (since the last update i.e. SR1?) noticed that term recognition has abruptly stopped working in Trados Studio.

I can literally search for a term in the linked Multiterm termbase and find it, but when I go to the segment with the exact same term in it, it is not found.

Exporting the terms, making a new termbase based on the old termbase and then importing the terms makes zero difference. The new termbase is also useless.

However:

- Terms are clearly being found in an F8 search

Versions used:

SDL Trados Studio 2021 SR1 - 16.1.6.4276

SDL Multiterm 2021 SR1 16.1.1.541

Fortunately, I don't use Studio as my main CAT but this is still unacceptable.
