Bug - stroke corners breaking

I created a simple button object, applied a stroke with radius on 3 sides. I then decided to test using a background image for the button (I’m still in exploration mode), and noticed that the one corner which wasn’t rounded suddenly renders incorrectly.

Worth mentioning that the live preview seems correct, but the intool render can affect the design workflow.

That’s very surprising. I have not managed to break rendering. Please send/attach your project with that button.

I couldn’t figure out how to attach it to this community, so posted it to a cloud link;

Excellent thanks, will fix asap.
