Glad you're enjoying the game! The combined actions showing x1.1 isn't a bug, more of a missing feature. Every combined actions gives a x1.1 speed boost on top of any familiarity the sub actions have, but the combined action itself doesn't gain familiarity beyond that. The next version adds an extra line to the tooltip showing the average speed boost of the sub actions.
If you're having any further issues/glitches, it'd be best if you could post about the on the discord server, as it's much easier to have a back and forth discussion there. I'd be happy to try and help fix whatever issue you're having.
