Each time you change your ingame viewing range, it's also changed in your minetest.conf. For example in my minetest.conf is now a line:
viewing_range_nodes_min = 145
So you could try to change it in your minetest.conf to a higher value before doubleclicking on bin/restarting.
Ingame you can use r to toggle to the standard max viewing range
Maybe it's just slow. My - sometimes doesn't react until I did something else like viewing my inventory.
Maybe you need to push also the <shift> key in combination with your +/= key, or is your key-board set-up a bit different (try keys like the ; , / ] etc. )
