An error occured while dublicating

How can i solve this problem? Tried to remove a row that had 90 % of emtiness, but it didn’t help me
What can i do?

Do you still have a lot of empty rows/columns/tables?

How many tabs do you have for your app?

no, not many)

5 Tabs

I think that i was caused by a lot of information in my app, but i’m not sure.
Before i added some interesting feature to my app, i could dublicate, but this feature took me 7 columns with info in profile sheet.

7 more columns should not be a problem… I would submit a ticket here to see if the support team can help.
