<ErrorMessage>Duplicated sheet names are not allowed

Hello everyone,

I got a problem with my Trados 2015 version, when converting an excel file after translation.

<ErrorMessage>Duplicated sheet names are not allowed (<sheet_name>). Check hidden sheet names as well.</ErrorMessage>

I use Excel 2016 and the Excel file has a couple of sheets. No sheet has the same name, which is impossible in Excel anyways.

Nonetheless, I got the error message above.

Did any of you experience the same problem and can help me out?


Thanks in advance,
