Delirium map craft and additional rewards interaction

I cant seem to get no additional delirium reward types if I use delirium map crafting option. Granted, I've only ran +-25 maps, but since I have both 8% for three extra reward types and 14% for a single additional reward type it feels like something is off. I understand that this just might be a streak of bad luck, but I thought I'd ask someone before I waste another beautiful divine orb on a thing that just might not even work as I thought it would
P.S. If I run deli by getting it through the atlas tree chance- I do get additional rewards as much as one would expect

(1-8/100)^25*(1-14/100)^25*100 = 0.3% chance, not enough to say conclusively but it's definitely starting to get fishy. I haven't heard of this being bugged, you could try testing it with leftover currency in Standard if you don't want to potentially waste money in league.

I hit it a few times so its working on my end.

Same here, I've gotten the extra rewards multiple times because I had so many free crafts.
