Logo still shown

The show logo option is only for the main schedule.

I should have tested the presence of a logo or not before trying to display it in the bubble.

What you can do is uploading a small white image with nothing in it, and set it as the logo for now. So the plugin has something to display.

I’m checking my code and it seems than I check the existence of the image, but not the right way. I’ll fix that in a next release but I don’t know when it will be.
