Hi,
I see that you’re still using LGC. It’s script on responsive height is pretty dated and is buggy. Tom stopped its support in favor of its successor which is GenerateBlocks. I’m afraid there’s nothing we can do about it.
I understand that you’re using it because you’re using sections but if I may suggest, consider using GenerateBlocks instead of doing sections + LGC so you don’t have to deal with this issue.
It’s much easier as you can use Gutenberg editor. Plus, it’s better in the long run as LGC is pretty much obsolete now.
