I did squad builder to see what I had for the 86-rated squad in Base Icon Swaps SBC.  I selected untradeable and no active squad players.  It loaded a number of active squad players and basically all my best cards (e.g., Scream Pique, flashback Fabregas, POTM Silva).  I hit the button on the top right, scrolled down to clear squad and when I hit it the squad submitted with no warning. 

Please reverse this.  I would never have submitted an 88-rated squad with a number of untradeable players worth in excess of 700k for an 86-rated squad SBC.  The EA Help just said "SBC submissions are irreversible" but that is obviously not true because it has been done before in the event of technical errors such as this.  Really disappointed in the customer service received thus far and will not play the game again or buy EA products until this is fixed. 

@EA_Eve @EA_Mai @EA_Cath @EA_Cade @EA_Cian @EA_Aljo any help is appreciated.  Thank you.
