How to Get A Correction with Guide Info

Here in Palm Beach, the guide for the local ABC affiliate WPBF (channel 431 and 10) is INCORRECTLY showing the 11PM newscast as a full hour from 11PM to midnight.  Then at MIDNIGHT, they list Jimmy Kimmel Live.  This is only incorrect for the MONDAY show.  However, Kimmel starts at 11:35 and not at midnight.  All the other days (Tues to Fri) have the grid showing the correct start of 11:35 PM.

This just started recently.  How can I get someone to look into this problem?
