Spells not updating

When I enter the Spell Editor and edit a character's spells, the newly chosen spells do not appear in the main Spells tab. They are still there if I open the Spell Editor again, but for some reason they just aren't populating in the main Spells tab. Also, the Spell Editor correctly shows the number of spells this character should have (3 level 0 and 2 level 1), but one of the level 1 spells never shows up in the main Spells tab.

This is what my Spell Editor looks like (correct):



And this is what my Spells tab looks like after clicking the green check mark (incorrect):



Edit: corrected number of level 0 spells available for the character.

 

I have never noticed that Rest button before! Silly, since I often click the Edit button right next to it. I suppose the extra spell didn't show up before because I hadn't rested the character since going up a level?

 

Actually, I just noticed that after clicking Rest, the Spell tab doesn't remain updated in the Library. If I reopen the creature from the Library later, it reverts to the screen shot I posted above, missing the second first level spell and all, until I click Rest yet again.
