Please add a valid /version output - the one you provided is invalid. This helps me a lot to fix issues faster!

If you want to stack spawners, make sure spawnerUnstackable is set to false, not true.

so i have tested with false but dont work too and if is false the description is so wrong
Should spawners be stackable

I've re-tested the issue - spawner stack fine when spawnerUnstackable is set to false, they stack up to 64 which is the Vanilla default. If set to true stacking no longer works.
I've adjusted the comment of the config flag nevertheless, thanks!
