Excel Reader Sheet name in loop does not change

Hello everyone,

I am experiencing a bug when reading various worksheets from an Excel file. The data is read in per sheet depending on its line position and then processed further. For this purpose, I use a loop, which first lists all sheets in the file and then imports the desired sections via an Excel reader. Using rules engines, I then get my flow variables, which I put into the reader. The first iteration works fine, but on the second the

sheet does not change (despite the flow variable changing). Is this something someone has experienced before?
