What is the behaviour in Path of Building?

I have a shield in PoB where I edit and add the crucible more for 3% chance to block spell damage/5% more maximum mana and save the item.

If I edit the item again the mod is still shown correctly, but if I click add crucible mod I see only the 3% chance to block spell damage attribute. After I edit a different crucible mod and go to save the item, I can see that it is applying just the spell block mod (showing a ~5% mana loss).

Shields do have a 3% spell block node so maybe PoB is reverting to the other T2 node.

How to reproduce the issue

1. Create a shield
2. Add the crucible mod for spell block/more mana
3. Save the item
4. Edit the item
5. Add any other crucible mod
6. Save the item
7. Note the removal of the more mana mod (spell block is retained)

Reproduce el problema en el editor de objetos usando el build code proporcionado y siguiendo los pasos indicados con un escudo y el Crucible spell-block/more-mana mod. Rastrea la ruta de guardado y recarga de los mods de Crucible; la corrección estará completa cuando editar otro mod de Crucible ya no elimine el modificador more-mana y conserve spell block.
