New Harvest Craft swapping Elemental Damages not working all the time

When using the new Harvest Craft to change a modifier that grants Cold Damage into a modifier that grants Fire Damage on a Jewel with Cold Damage over Time Multiplier, the game tells you "There are no valid Mods for this craft on this item" even though Fire Damage over Time Multiplier exists.
This does not happen on other base types such as Staves.
Changing Increased Cold Damage to Increased Fire Damage does work however.
