Hiya Bratch
I've just installed this extension in FGU current build 4.10 on a Mac. running Catalina 10.15.7
I've disabled all other previously loaded extensions.
The Rob2e spells are not being parsed still.
I've checked some common ones like "Burning Hands" such as used in your example.
If I switch to PHB versions, then it works as expected.
NPC's work fine
I had thought I understood that your support extended to "5e Effects Coding - Spells"
What have I done wrong?
