Hello freshman84 & Piggybank Studios,
Ah thanks - yes, I also managed to reproduce an incorrect behaviour yesterday by mashing buttons on the imports window when nothing was yet being exported.
It looks like I am missing protection against pressing A on this window when it is empty. Hopefully this is the underlying cause of these observations.
I'll get a fix pushed out this weekend.
EDIT: This is now fixed in v1.6 👍
