Studio 2019 - corrected segments (errors) in running translation project still shown as 99%-matches in TM

Question

When correcting an error in a segment I already confirmed at an earlier stage in a running translation project this corrected match is still shown as 99-percent-match in the TM after correction.

(Example: *I need help.* correct translation: *Ich brauche Hilfe*.
former (wrong translation): *Ich bruche Hilfe* (still shown as 99-match in TM after correction of the error).

Although I aprreciate the possibility to have various matches (multiple 100%-matches) for identical source segments, I do not want to have errors in my TM. Is there anything I can do about this? Thank you.

Hi Angela Kosler 
 I recommend turning off "Prefetch (lookahead)" and see if that solves the problem: 1. Go to File, and select Options. 2. In the Options dialog, in the navigation tree, expand Editor. 3. Select Automation. 4. Under Translation Memory, clear the Enable prefetch(lookahead) mechanism checkbox.
