Divine Dragon Runes and Glyphs

I was looking back into my dragon’s runes and glyphs, to see if I could add any more and I was shocked to see that my specialised runes and glyphs for Garmir, Cleillis AND Re’Gyn all had a spell boost of +0!! This is even at expert level. Weirdly, this does not affect my Hildr, who has all of its spells working fine.

Can someone please explain what is happening with my runes? If it’s an unsolvable glitch I may as well salvage the epics because they don’t do anything else.

Some screenshots would be helpful if you could. Mine all appear to be fine

Here are some screenshots

Sure, no problem.
