String height on a Gibson acoustic guitar should be 4/64 at trebile side and 6/64 at the bass side measured at the 12th fret when set at the Gibson factory. It's odd that the treble side is below spec and the bass side is way above spec. Either there is too much neck relief,too much humidity for your guitar, someone filed the saddle wrong. somthing is in the saddle slot and the saddle is not all the way in the slot, or your guitar needs a neck reset. Gibson would not ship a guitar from the factory with the set up this bad. Factory set string height for a Taylor guitar is 3/64-4/64 on the treble side and 5/64-6/64 on bass side. Martin guitars set the action at 4/64 on treble side and 6/64 on bass side.
I set up my Gibson Hummingbird early 60' to formula : 2/62 " string height on first fret , 4/64 " on 1st string ( 12 fret) and 6/64 " string height on 6 bass string ( 12 fret) . Strings I use now = DR Sunbeams Acoustics extra light 10-48 .
This is actually Gibson factory setting that I find the best ( except for factory strings gauge 12-54)
