Hi guys, I read your responses again carefully and went back to the pump, used the water hose trick I learned on youtube and did identify the drain plug was letting in air as you all suspected. I removed and added teflon tape and pool lube to oring and tightened back up. I had not realized how clear the water should be in the pump basket!
This resolved the issue of my filter blowing back when the pump stops. However, I think I still have an issue as the pump takes a while to prime back up and when it does I then have bubbles again! My pump is 35 ft from pool and higher than water line.
I made these short videos and if you have a chance to watch them I would love your help. Thanks in advance!

Pump running great no bubbles, I shut it off and water stays in pump basket.
pump-vid-2
I restart pump and quickly all the water in pump basket disappears.
pump-vid-3
Pump cycles for about 30 seconds still not flowing properly.
pump-vid-4
Around 45 seconds appears like going to work then water empties again.
pump-vid-5
Around 1 minute into cycling after being restarted pump is running with a lot of air bubbles
pump-vid-6
I cracked bleeder on filter which lets out new air and pump basket is now clear of air bubbles.
Is this cycling normal and why do I have new air bubbles? Is this related now to my pump elevation and distance?
