Trouble with Pretranslation

I have to pretranslate a 65k+ product excel using both Tm's and DeepL. I pretranslated once (marking the "Use AT when no result in TM), lowering it to 75% (which was a mistake), this made all segments which were vaguely similar to be translated with the same translation it first encounters of the type. So, here is my problem, I tried pretranslating again with a higher value (95%) so it would stick to the TM very tightly and just AT all the rest...what happens? That when the file is pretranslated all segments are empt with an AT, if I click on them, the same wrong translation will appear in the segment although in the top left box it appears properly translated by the AT... any idea what I can do? Thank you
