Сonverted lead is not updated during merge

[AndreiVysotski]

Dear community, 
I'm trying to merge several leads into a converted lead. But the fields on the converted lead are not updated from duplicate leads, although the merge was successful. Error message: Cannot save already-deleted object: id = ****************(Converted Lead ID)
Is there any solution?

Hey @AndreiVysotski - Please reach out to our Technical Support team at Support@validity.com with the App Log from your convert job so they can investigate further to determine what may have caused this behavior. Thanks!
