Property "PluginDynamic.reason" is not defined on Response Table Import - by: blocka

I deactivated a survey, and then immediately reactivated it.
I then went to Responses->Import from deactivated survey table.
I select the only response table available, and when I clicked import I got this error:

Property "PluginDynamic.reason" is not defined.

I'm using version 2.64.7 (170404)
