figures German to English need to be confirmed always

Hello, I have a weird problem with figures when translating from German to English. Trados converts the dots to commas (as it should be), but I have to confirm every single 100% match figure. And after this, the subsequent figure in the next segment changes to a 99% match ...and so on. I haven't found anything in the settings, can anyone help me with this?

Regards,

Elke
