Blade appears to be warping and scalping grass. Every now and then the blade digs into grass and stops mover.

What height setting are you using, is the blade visibly straight and is the ground relatively smooth and level?

Next to highest.  And mostly level flat ground

The blade is straight but somewhat flexible

Does the mower set level? sometimes the arm that sets the front wheel height
comes off.

Appears to be ok.  But worth a check

That’s really strange. Somehow the blade would have to get close to the ground. Doesn’t make sense...

Very odd. Is the blade installed correctly? There are some words stamped on one side of the blade that say "this side to the lawn" or words to that effect. Make sure they are facing away from the mower and toward the grass. Along the same lines, is the bolt that holds the blade good and tight? Maybe it's loosened and there is wobble in the blade? Can't imagine the blade is flexing. Mine certainly doesn't.
Perhaps take a picture of the underside of the mower and post it here?

It's because the wheels lock up, when the self propel system is released. Very annoying in tight spaces (when you cannot push the mover forward after stopping. Depending on the speed, the mover digs in and scalps the lawn.

You need to release the SP before reaching a stop so you can roll forward slightly.  Then the wheels will not lock.  The locking is a safety feature to prevent the mower from rolling backward on an incline.
