Unable to enable individual themes for sites, anyone else having this issue?

Just noticed that if we have a theme that is disabled sitewide that we want to enable on one site, when we edit the individual site and check off the theme we want to enable and then save, the setting is not saved. The theme is no longer checked as being enabled once you click the "update options" button. This applies to a dozen or so themes we on the install.

Example: If you want to enable a site theme for a specific site, you would go to "Site" link (in super admin section) > click "edit" on site of choice > and then you check individual themes that you want to enable in "Site Themes" section on top right hand side of the page. When we do this our checked themes simply don't save.

Anyone else having this issue?
