Actions and stuff 1.2 (marketplace add on) doesn’t work with default texture pack on realms

I cannot use Actions and stuff on my realm server with the default texture pack. It’s really frustrating; I can use other texture packs and place them above the Actions and stuff resource pack but because I cannot move the order of the default texture pack I cannot bypass the slider feature . (Which I’m assuming is the issue)

On worlds that aren’t on realms the actions and stuff add-on/texture pack works perfectly with the default texture pack.
