EPMInsertedMember - Caption disappears after refresh

Hello experts,

I have the following issue. I successfully set up EPMInsertCellsBeforeAfterBlock function to insert two columns before my report.

I successfully set up the caption in the new EPMInsertedMember functions according BPC430.

So far, so good.

However, if I refresh, the captions disappear.

Did anyone else encounter this issue and knows how to solve it?

Regards,

Denis
