[Crafting] Unlocked "Suffixes cannot be changed" metacraft but somehow it doesn't show up

Good evening (at least in Germany)!

As the title states, I've killed Yriel in a Mud Geyser Map, clicked the crafting recipe which spawned after her death, the notification popped up and I was pretty happy.
Turns out, I'm either too stupid to find it or the recipe somehow hasn't been activated at my crafting bench. Of course I've also double-checked this with a variety of items with open pre- and/or suffixes, all with the same outcome.

Searching for "suff".
Searching for "chang".

I couldn't find any corresponding posts or reports here so I created this thread hoping someone could clarify the topic.

Regards and hats off to GGG for this awesome league,

Bumpety boo.
