It must have been damaged somehow, or the internals are leaking air.
It's very rare for any mechanical gauge to be that far out, even very cheap ones. Ive never actually seen one of any brand that bad that hasnt been damaged.
Even a cheap sub £5 gauge from a pneumatics place.
Either way, time for a replacement
