The way gALCX works is by wrapping your ALCX to gALCX right, that means the amount of ALCX per gALCX you can get when unwrapping will increase, but the amount of gALCX actually won't.
When you're on the farms page and go to the gALCX wrapper, select "unwrap" and click "max"; in the field below the input it will show you how much ALCX you would get for unwrapping.
We're going to improve the UX on that part so it's easier to see and understand what's going on in the future.
