Hello @jdavid, thank you for your post and welcome to the forum 
I believe the weird behaviour you’re describing was already discussed here at some point: List view (& Grid) - more than 11 rows?
Would you mind having a look?
As for InkScape - would it be possible for you to open a new forum topic regarding this particular issue so that we can possibly find a way to resolve it?
Thank you again,
Yuriy
