There is a thrust button inside the suregrip. The end of the axle buts against it for adjusting the axle end play. Sometimes the pin that holds them in the suregrip breaks and one half might drop out or get lodged when removing the axle.
Remove the axle in question and try to look up the housing tube with a strong flashlight to see if its in place or not.
Could be your bearing race isn't seated all the way also.
Looking into the axle tube. There is no button in this one.

This is a set of thrust buttons with the pin that has been taken apart. The red arrows are the buttons, the blue arrow is the pin that holds them together. The buttons are inserted one on each side. If the pin is broken, one of the buttons could be stuck to the axle when removing and become dislodged not allowing your axel to go in all the way.
