Hookpad randomly putting rest in bars?

Hi guys! Why does my hookpad randomly skipping melody bars? I mean I didn’t put a rest note but when I pasted the melody line it skipped random bars so there’s unwanted gap with the underlying harmony? There’s no rest note to remove during the writing session so I can do nothing. I need to save the project and load it back and that’s when the unwanted rest note will appear hence I’ll be able to remove it. Help.

ps: sorry for bad english.

Do you have a link to the tab, or pictures? A bug report like this should have some sort of evidence.
