Analysis not showing fuzzy matches

I colleague of mine is experiencing a problem when analysing files during the project creation process: no fuzzy matches are showing in the analysis report, but when opening the bilingual file in the Editor there are many fuzzy matches showing up when clicking in the target segments. 

I have found a workaround to temporarily solve them problem: I have re-analysed the files applying the "Report internal fuzzy match leverage" option, the re-analysing one more time deactivating the same option. In doing so, the normal fuzzy matches (i. e. not the internal fuzzy matches) appear in the report.

Is there any known bug causing this problem?

The version is SDL Trades Studio 20014 SP2 - 11.2.4409.10

Thank you very much in advance,
