Pat and Jason,
Do you see that issue when you try to edit any theme?
Jason,
Are you using a custom or standard theme on the calendar page? If a custom theme what was its base theme (so I can report this issue)?
In the meantime, you can add this as a CSS resource on your page to adjust the color of the filters on hover (it will also affect the view picker on the calendar):
.nx-editor-header .nx-actionselect :hover { color:black; /*color of the text on the filters*/ background-color:gray;}
If this affects other buttons and / or filters on your page you can add a specific class to your calendar and to the CSS resource to only affect the calendar.
Thanks!
