Shower guides move around

Hi,
We ordered the 10-216 shower glides and installed them today. I'm attaching a photo to show that they slide back and forth away from each end of the door frame therefore causing the doors to rock on their ends. Are they suppose to somehow stay put on each end of the door frames? If so, can you please guide us on installing them properly as this has become a safety issue causing unsteady glass doors.

Thank you for your patience. I'm sorry to hear you're having trouble. I'm not sure what the issue may be, though. We talked this over with the manufacturer and they told us that it should just slide into the screw rail at the bottom of the door. There's no real trick to it, and once in they should stay put. Could it be the rail is bent or loose in some way, making the 10-216 rattle?
