Updating parameters in DP2 hangs at parm 161

When I go into the parm tab on DP2 it starts getting all the parms on my Pixhawk. Then around 49% at around parm 161 out of 300, it hangs.

Is this a bug?

I can get all the parms if I press the screen to retry. It takes at least 3 tries to get all the data. I have to retry as soon as the first one fails. It looks like there is a timeout going on.

There is no problem getting parms from MP however.
