Can't erase config 40gig QSFP Int's Arista Eos

Hey there,

I'm having a bit of trouble with some interfaces on a network I inherited. It seems someone tried to configure all the 10gig interfaces and then enable 40gig. Now I can't edit and remove the superfluous interface configs.

ill paste a modified version of the config below. Also these are 7050QX-32S. Before anyone says anything yes I know its a ridiculous model, not my choice heh.

interface Ethernet7/1 speed forced 40gfull switchport trunk allowed vlan 1,69,420,1970-2020 switchport mode trunk switchport ! interface Ethernet7/2 switchport trunk allowed vlan 1,69 switchport mode trunk switchport ! interface Ethernet7/3 switchport trunk allowed vlan 1,69 switchport mode trunk switchport ! interface Ethernet7/4 switchport trunk allowed vlan 1,69 switchport mode trunk switchport ! 

Memes aside, is my only option TFTPing a config up and ingesting it? Or is there some voodoo trick in the CLI I can do (other than making them 10 gig interfaces)

DiscountCatalyst1(config)#int et7/2 % Interface does not exist 

I tried searching but after no results I'd figure I'd ask you peeps.

Hope you're all doing well
