Does anyone have this similar GNG sprocket??

Hi guys,
Im in the process of upgrading to #25 sprockets and chain on the gng 60v650w chain reduction,
and was wondering if others have the similar 11T sprocket set-up.
Sometimes Chinese factories change parts on the same product.
Not sure if all come like this or not
The is the way it came when I ordered it. I was able to get the nut off with an airgun at a garage. I recommend doing that, as others have mentioned
I ordered this sprocket:

13 Tooth 10mm Dual D-Bore Sprocket for #25
here:

Should that small gng sprocket just slide off, because mine doesn't. I didn't want to try and force it off or pry it until I was sure.
Here are some pics:

Any advice is greatly appreciated as always, thx in advance!

Update...
Sorry about the new thread but if anyone is replacing that small sprocket then
it does come off but its on their very tight even with the nut off
It took mr a while but I did decide to pry it off and wiggle.
At first I though the inner sleeve was connected to the sprocket but its not thankfully
