When you say #6 wire 3 wire - you mean a cable 6-3?
With 2 hots, neutral & ground ? (based on dryer connection seems like this is what you have)
What size breaker is feeding the sub panel?
You do need a grounding buss/bar

Is this wrong?
I tested the dryer for 10 minutes and all seemed fine. But i would like some more input. thank you Joe
So you have a 30a breaker in the sub panel & used #6 wire to connect the dryer?
You only needed #10 wire, but larger is OK - as long as the breaker is rated for that size wire
You need 2 hots, neutral & ground to a 4 prong outlet (sound slike what you have)
Dryer then needs a 4 prong cord
Other then the ground bar sounds like everything is OK
