QA Checker Studio 2015: Extra blank spaces detected generates tons of false positives

Hello!

If both source and target contain one or several tags surrounded by single white spaces, the QA checker seems to ignore the tag in the target and gives an alert for extra blank spaces although there are no multiple white spaces present:

Is this a known bug or is there any way to tweak the settings to avoid such false positives (short of re-creating the feature with a regex myself)?

Thanks a lot in advance for any suggestions!

Kind regards,
Raphaël
