Hello,

Kalu'ak Whalebone Glider can be used as a ground mount too, but I cannot summon it by the addon.

Did you select the glider as a ground mount?

Yes, I did. The Mount button is grayed out at the bottom of the window too.
But changing the mountType in the lua from 1 to 2 do the trick for me.

Mb you used it in classic locations, so flying mounts can't be used there. If you can use any flying mounts please write about them.

Thanks, its working fine.

I can use the glider as ground mount in Azeroth, Strange, maybe blizzard didn't want it that way, but it works.

Fixed, added some else flying mounts for use in the classic locations.
