Yes the paper should be stapled to the wood should have a an overlap on one side also might want to try to fix the compression in yours bats so get your actual r value

if you want to drywall the basement you want to remove those batts and replace them with unfaced batts, rockwool or XPS. Rockwool is moisture resistant.

DONT staple it, (if you can) … remove the paper prior to sheetrock. You do not want an additional vapor barrier holding in humidity.

If you remove that vapor barrier that's glued to the batts you damage the batt as well vapor barrier should be secured if op staples this vapor barrier then they do not need a poly vapor barrier as well again I still suggest that local coding is checked but manufacturer says to secure the vapor barrier that is on the batt not to be just removed or else the r13 value that is up is no longer r13
