Frogs killing magamcubes don't drop froglights but magmacream. DATAPACK Issue

I have a problem with getting froglights.

I have set up a magma cream spawner in a bastion in the nether. The nether was discovered in 1.18. I got frogs from the overworld from three different biomes towards that magma cube spawner in the nether. 

When the frog eats a small magma cube, the frog will drop magmacream instead of froglights. I also tested this in a creative world, and there they do drop froglights. Also going into the nether in a creative world does make them drop froglights. 

There must be something wrong with the magmacubes in the nether I guess.

The problem has been found: I was using a datapack from vanilla_tweaks to get mobheads which was overwriting the loot table for froglights.

Thank you in advance.
