Greetings, I initially wanted to report a bug, but was not able to register for a Bugzilla account.
Here is the bug. There was an issue when I opened a document with Calc from an Excel sheet .xlsx. Some cells if it had colors in it, the Calc opened with duplicate. For example: Name/Test The Calc opened it as Name/TestName/TestName/Test The amount of repeating patterns, I have not been able to find a pattern. Not all cases with a color change had the duplicates. So I still wasn't able to find that pattern either. Thanks.
