The Cimarron will be similar where it meets the floor.
If it's only an 1/8", I would use some shims and caulk the base.
You can also cut down the flange some, and that would work. In those cases I've used a metal repair flange drilled through the tile and concrete to hold the closet bolts.
If we had been there, you would have had a working toilet before we left the job.
