Blazing Flare node does not properly convert shock chance

The “Blazing Flare” node for Runebolt is not converting shock chance from items, specifically Tome of Elements. I’m still in campaign so i’m not able to test whether this is also the case for shock chance from weapons or from passive skill tree. Shock chance from the skill tree itself (Orderly Conduit) is still converted properly.

This is in Offline Mode.
