I have Wyll multi-classed lvl2 fighter/lvl 5 wizard. I just leveled wizard to level 5 now and looked at my inventory to see what level 3 spells scrolls I didn't have to choose what to learn at the level up window. I only had 4 missing: Vampiric Touch, Sleet Storm, Hypnotic Pattern, and Counterspell. I had the other 23 as scrolls.

So I chose 2 that I didn't have, and then proceeded to learn the rest via scrolls. The problem I ran into was that 8 of the 23 level 3 spell scrolls are indicating that my wizard level is too low to learn them. The level 3 spells which are saying my level is too low to learn are as follows:

- Conjure Minor Elemental
- Stoneskin
- Wall of Fire
- Confusion
- Greater Invisibility
- Phantasmal Killer
- Polymorph
- Dimension Door

All of the above spells were available to learn at the level up window (along with the 15 lvl3 spells I did learn via scrolls). So what gives? Is this a bug, or a 5E rule I'm unfamiliar with?
