Can't confirm import challenges from template via GUI

[Jcodeerd]

Expected behavior

A button, or command I have to input in order to confirm importing challenges from a default template.

Observed/Actual behavior

after getting the message asking to confirm I get an exception in my console:

java.lang.NullPointerException: Cannot invoke "java.lang.Boolean.booleanValue()" because "value" is null
