I have the settings at Base ISO - 200, ISO Limit - 6400, and shutter at 1/60th. In bright daylight, the shutter will stay at 1/60th and the ISO will be up over 1000 at times. Isn't the ISO supposed to stay at the base and only raise when the shutter is at the limit?

Are you setting the shutter speed via the dial, or setting it to 'A' alongside ISO (creating 'aperture priority' mode)

A shutter speed (or any setting) set manually on a dial will never be overridden by the camera.

This is probably it.

The OP's story is very strange, in bright daylight SS @ 1/60, and 1000+ ISO??? what aperture was selected?????? with an ND filter??? Something is not right.

It is almost impossible that SS will stay at 1/60 in bright daylight, and having to bump ISO over 1000, even with a very small aperture, unless the SS is manually set at 1/60...

we also need to look at the way the scene was metered
