Fields Builder - Possible Bug?

I have a field called State. Its a drop down box that I have on the Join, Edit Profile, View Profile, and on Search.

On the simple search page it's showing up as a Multiple Select box rather than a single drop down. I double-trippled-checked it and it's set to Selector (drop down).

On all other pages it's displaying correctly.

Any ideas?

I am running dolphin 6.1.6

Below are the screenshots of both my Admin panel (fields builder - simple search) and the screenshot of the field on the actual webpage.

And FYI...This is happening on both my test server and live. Both are configured exactly the same.
