Simple bug in the snippet of Arcane Recovery. The snippet reads:

Once per Long Rest, whenever you finish a Short Rest, you can choose expended spell slots to recover. The spell slots can have a combined level up to {{(classlevel/2)@roundup,max:6}}.

The description reads:

You can regain some of your magical energy by studying your spellbook. When you finish a Short Rest, you can choose expended spell slots to recover. The spell slots can have a combined level equal to no more than half your Wizard level (round up), and none of the slots can be level 6 or higher. For example, if you’re a level 4 Wizard, you can recover up to two levels’ worth of spell slots, regaining either one level 2 spell slot or two level 1 spell slots.

These two do not agree. The maximum combined level is not 6. The maximum individual slot level is 6. This is effectively capped at wizard level 11 under this wording.
