I will package a new release tomorrow and the deployment is done within a few hours.

I revised it again - I'm pretty sure it's fixed now! (for the next release)

Fixed for the next release.

Hmm... let me check that again...

This is clearly my fault - I will merge this bug with another entry I just got. Please see here: https://support.davinci.tools/communities/1/topics/814-ga-breakingmergingmoving-field-headers

Oh! I have made some changes to the heat map handling and this is certainly a consequence. If it too annoying, for now, you can go in Da Vinci Tools Options and disable "Heat Map" under GA Options. I will try to fix this promptly and release a new version.
