Popup menu not expanding fully

Hey all, I’m on Rhino 8, and since I’ve been using it my popup menu isn’t expanding to show all the buttons. The below screenshot shows the menu when it’s floating on the left, and on the right is when it’s ‘popped up’ - you can see that it’s got a flyout option at the bottom.
I’ve tried ‘Size to content’ option, but no luck.

Any ideas?

Edit: I know I can use the ‘Cascade as menu’ option under RhinoOptions>Toolbars>Size and styles, but I’m losing the formating breaks that I like.
