Any idea why would Tasker bubbles show as much smaller than regular bubbles?

In the attached examples, I have given Tasker bubble and app bubbles same exact icon (from icon pack) and same exact settings (colors, border, bubble size).

And yet:
– They show differently in the bubble list (tasker one has a shadow, app one has border)
– Tasker one is much smaller on the watch

I have also noticed that “Border” slider does not seem to have any effect on Tasker bubbles, they are the same size regardless.
