It's hard to answer this question unless you help us by showing screenshots of how the numbers/dates are recognised.  For example:

You can immediately see here that this date is not recognised as a date because the number 16 and the number 2020 are underlined separately as two tokens.  In the meantime the translation has a date that is probably seen as a complete token.  If it was in the source it would be like this:

Like this you can see how the QA tool would think there is an extra number.  Now, in my example clearly the extra number is in the source, bt the same thing could easily be the other way around.

So perhaps take a fresh look at your segments with this thought in mind and see whether you can understand why the message is what it is.  It's also worth noting that in Studio 2021 you have much greater control over what will be recognised, so if you're using this version you might be able to fix it by changing the language resources on your TM.
