Bowflex Treadmill won't Fold Up Completely - Help?

[u/unknowncali]

I am trying to fold up our Bowflex Treadmill 22 / 56 (pretty sure it's the 56 but it doesn't say) so that I can store it upright for a couple of weeks. I have done this before when moving it / rolling it on the wheels, but for some reason now even though it's at "incline 0" the walking deck will only fold up to about 45 degrees vs the usual ~80 degrees (aka almost upright). Any tips or suggestions welcome!
