LG fridge door gasket replacement - french doors

HI,

I ordered the proper gasket for our LG fridge, model number LFX31945ST. The door gaskets are moldy, so we want to replace.

The left door has a flapper which seems to cover the gasket, and it is unclear how to remove it in order to replace the gasket.

I have searched here and on the web for any instructions or videos on how to replace the gasket, but I haven’t found anything. LG’s website doesn’t have anything; neither does the fridge manual.

Any assistance would be great! Otherwise, I will just try to clean off the mold and return the gaskets.

Thank you!
