Import from OSE Membership - bug "#1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 1"

I am trying to import users from OSE Membership but after clicking import I'm getting an error:

1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 1 After checking my emerald control panel I can see that part of users and first plan has been imported. Can you help me to fix the problem?.. Thank you.
