Sam Clemens would be proud. Looks formidable.
To clarify - I think your proposed grammar is valid but the phrasing is uncommon. It’s not a phrase I would expect to hear. Though I would understand the gist of what you’re expressing.
Best sounding recommendation probably depends on context and ‘the thing’:
There’s a concept I don’t understand.
There is something in the box I don’t recognize.
There is a feature of the coffee machine I haven’t figured out yet.
There’s a Greek word in the original text that I don’t know.
My guess is it’s likely not a bug but an unexpected (by you) interaction of the tool script with whatever layout you’re doing.
If you can post example code demonstrating the problem someone will probably be able to pinpoint what’s happening.
Sounds like you found a workaround.
There might be some tricks here that could help too:

Enjoy! And watch out for AT-ATs!
