For simplicty you can specifiy those options in the Extra options because it will accept them twice. I believe it wont accept keepalive if the ping options are set, but you can set the ping options twice, and keepalive is just a simplified way to set the ping options.
Other option also is to set the value on the other side of the vpn to be compatible with the 7 second reset.
I see this more of a feature request to have ALL the options be adjustable from the GUI, and I’d agree!
