no its normal
they do a start up sequence etc, somtimes when you remove them they can "stick"
as soon as you install it, they will just revert to 0 and be fine, its nothing to worry about
ive removed lots of guages which hvae been like that and never had any problems
had a greddy temp guage once which the needle was on 120degree (all way round to the right), installed it, it worked fine
