Roll20 5E character sheet v. 4.21 keep losing my elemental affinity and agonizing blast damage additions in attacks

Every week I log into to roll20 for the last 8 months or so, I regularly have my my CHA adding to spell dmg attacks for both Fire and Eldritch Blast. It seems to have about 50% of the time, last week being the most recent.  No one else is set up similar, so cannot tell if it the campaign or not.  But I have to go through all of my spell attacks and re-add CHA to the damage.  Nothing else seems to change as often.

Once you have them corrected, try changing the name in the attacks section. Or better yet, change the damage field in the spell instead of the attack section. The sheet builds the attacks from equipment and spells that have attacks in them, so sometimes data can be overwritten.

Thanks! That makes sense, if the spells overwrite modified spells.  But really they should not.  They can really only make things worse. Won't create new attacks with different names, just create 2 attacks when this happens?  Like "Fireballz" (modified) and Fireball?  Is that really an ideal outcome? I've seen this with weapons. I wonder if a better thing is for the sheets to account for agonizing blast and elemental affinity?  But even then, the spell should not overwrite the existing attacks, overwriting user intent is inherently a bad UX/Choice. If they the attacks are messed up, likely by the user (e.g. me), the user can delete the attacks and spells and re-add.
