Armor bar display doesnt seem to work with custom armor values

I am currently working on a datapack in which i have made some custom armor sets, while working on these i noticed that the armor bar display seems a bit off.

when equipping only one item it works fine(see image 1)here i have an otherwise unmodified potato that i made equipable and gave it +2 armor.
If i now equip another piece of vegetable(a beet, see image 2) the armor bar now displays 4 armor, but hold up! The potato gives +2 and the beet gives +4, and +2 + +4 = +6, !! but thats not what is displayed. It seems it displays the armor value of the most recently equiped vegetable instead of my current armor

For this next exhibit, i have equiped a tougher beet, this time giving +10 armor whiole the potato remains unchanged, i equiped the potato last so the armor bar displays 2 armor.
I then disable natural regen, heal up, and apply 10 damage from player_attack to myself and i take 4.5 hearts of damage (see image 4)

When i repeat the experiment but equip the tough beet last, my armor bar now displays 10 armor and i take only 4 hearts of damage(see image 5)

Another variant we can do is to equip beet, then equip potato such that the armor bar displays +2, if we then unequip the potato, naturally we lose 2 armor so we are left with 0 despite having a real tough beet on our feet. (image 6)
Now if we take 10 damage from a player attack we take full damage(5 hearts) and receive no damage reduction :( (image 7)

I have scouered the internet for people sharing my sadness but i have found none so i am open to the possibility of this being my fault(barely) as i have limited experience working with datapacks.

I am also aware of potential workarounds such as making a score that stores armor values and changes as you equip something, then changing players' armor attributes with the /attribute command but this seems like work and i’d rather not.

If you need anything more from me i would beet( : D ) more than glad to help :)

Would be most lovely to hear from you soon :D

Potato:

/give @p potato[attribute_modifiers=[{id:"armor",type:"armor",amount:2,operation:"add_value",slot:"head"}],equippable={slot:"head"}] 1

Normie beet:

/give @p beetroot[attribute_modifiers=[{id:"armor",type:"armor",amount:4,operation:"add_value",slot:"feet"}],equippable={slot:"feet"}] 1

Tough beet:

/give @p beetroot[attribute_modifiers=[{id:"armor",type:"armor",amount:10,operation:"add_value",slot:"feet"}],equippable={slot:"feet"}] 1
