After buying the +1 enchantment level power, the first enchantment I did worked correctly and gave me Protection V, etc.
However, subsequent enchantments have not received the extra level.
Reloading the game did not fix it.
Update: After playing some more, the effect seems to only work some of the time. When I do a bunch of enchantments in a row, it sometimes only activates for a couple and sometimes works for all of them. When it doesn't work, the enchantment also isn't giving me xp towards the enchanter job.
I'm playing on the most recent 1.18 version.
