Tier Incompatibility?

[purple crobatchop]

This is my team I am preparing for the DPP OU tier. Whenever I try to change the setting to DPP OU a message like this comes out "The generation of your team is invalid for that tier." but I don't see anything wrong. Help?

in that case the error message would be

The following pokemons of your team are invalid (ban, level, moveset, item...) in DPP OU, hence you can't choose that tier: Salamence.

which is not the case here
