We recently upgraded to PPM 15.2, why is the word 'to' now partially covered on the date range filter?
If the below CSS code is not included in any 15.2 UI themes, this issue will occur.
Out of the box themes were automatically updated to include this. However, any custom UI themes will need to be manually updated with this change. Once this is added the theme's CSS code under Administration -> UI Themes, the word 'to' will appear correctly on the filter field.
