Minimum match value in Pre-translate setting cannot be lowered than 70% in my Trados Studio 2021.

Hello,

I hope to get help to know why I cannot change the minimum match value lower than 70% for pre-translating a file.
The field for the value turns red if I put a number lower than 70%. I tried to delete and reinstall the most updated version of 2021, but the problem persists.

May I ask anyone to help me understand why I cannot change this value and how to resolve it to set the values with whatever I want, please?

Thank you in advance for your help!
