Concordance and TM Lookup behave strangely

Hi

I don't know if you experience the same, but after installing CU8 we have issues with Concordance and TM Lookup. Some segments that we know for sure, they are in the TM are not  found by both. E.g. "Freundliche Grüsse" is an extact match that I can find when I search the TM in the TM view, but it is not found by Concordance or by Lookup. I reindexed the TM, but nothing changed.

Any thoughts?

Thanks,

Angelo
