Minimum Match Value: This is the degree of match that must exist between a source document segment and a translation memory segment in order for the segment translation to be offered as a match. The default is 70%, but you can set a value between 30% and 100%. The selected value is inclusive, meaning that matches with your exact selected value are also included in translation results.

However if you are getting false positives then I would recommend you review this article that covers how to maintain your TM: https://gateway.sdl.com/apex/communityknowledge?articleName=000004791

I would also say review if you have other settings that could be impacting your user experience - such as look ahead 

Thanks Lydia

My problem is not with the TM fuzzy matches, but with the excessive false positives flagged by Verify - to the extent that the Verify result list is almost unusable because of its excessive size,

As I mentioned in my example, I cannot understand for MMV 67
Application -> application OK (defined in the TB)
Applications -> applications NOK, flagged
