Excel Engine 2018.2 protection password gets lost


we open a workbook (having protection and a password for it) with IG excel engine. After writing data to some cells we then save the workbook with a different name.

This copy is still protected, but doesn't have a password for the protection anymore. The user can simply press the "unprotect Sheet" button and is not not asked for a password.

This is a huge problem for us.
