Why don't my waiver claims stay after I enter them

This has been happening for a long time but I put in my waiver claims and then I go back to it by clicking on your waiver claims and they are gone every time. I then have to enter them right before the 2:00pm waiver time and make sure I save it or I won't get my selections. I just did it again now, went back to it and it says no waiver claims.

Is there anything I can do to feel confident that they are going to stick after I enter them once?

Thanks in advance!

I hit the save button (I forget it's exact label) before leaving the waivers page. Otherwise, the attempted claims are lost.

Make any minor change even if it is to move someone up and then back down. Then save.
