forgot to mention a fix for this issue too!
1/2in PVC with end cap glued on one end, cut to the length of the webbing pocket the pole goes into.
Use "Tear Mender" fabric glue, Loctite Vinyl and Fabric adhesive, or I think gorilla glue could work but might be messy. Apply glue all around the outside of the PVC, and push into the webbing pocket until bottomed out. Allow for it to dry then re-insert the pole and you're good to go.
