Too big step of changing the line distance

The interline distance settings changed yesterday. The step used to be 0.5%, and now 50%. Is this a new feature that can be disabled, or is it a bug?

Update: it’s appears in existing files. If you create a new file, the adjustment works normally for a while, then breaks down

What command exactly are you using? What is “line distance” or “interline”? How are you changing it?

I’m using mouse adjustment for line height. It’s works normally on adjustment by points (adjustment worrk by 0.5 points - 24-24.5-25 etc) but jumps by 50% instead of 0.5%
