Ok. Thank you for the hint. I'm going to bundle the next time.
But the format of the post was ok?

Btw, the Fix was little but the error was big.
This fix has affected a dozen pages and several hours of research.

In 99% of the time the error did not occur, the component had to be integrated with certain settings and the user also had to perform certain actions. If the component was included normally, the error never occurred.

That's one small step in the code, one giant leap for the component

Nevertheless many thanks for the review and the work :-) Keep up the good work
