Highlight function not working properly in review mode

Hi thanks a lot for a great app.
ive tried to make review cards using ‘mask highlight’
When i review cards that I’d made, the highlighted phrases arent masked fully but partly.
(Yellow highlighted phrases ‘s. Pneumoniae’ in the pictures below. The phrase S. Pneumoniae is not fully masked in the first picture yet it should be)
The same problem occurs both in iPad and iPhone

Its not working as it seemed in trial videos made by the developer team


Is it convenient for you to send your operation process to us in the form of video?

Kind Regards,
Support Team
