Grav Comments Plugin not working for me

I cannot get the Comments plugin to work reliably. Right now it does not not save the comments to the data file in the data folder. It does send an email, but not every time. On the page that has the comments form, I have cache_enable: false. I have the form process set to post comments before email. Tried it both ways. Does anybody have any suggestions of what may be causing this?

Please create an issue on the comments repo:
