yea, i did use a few long clips.
i moved the WAB to where i wanted it to be, but when i go to the export window it still says 7hrs.

thank you so much for helping me.
Try a different export setting from devices and check the "Share Workarea Bar Only" checkbox:

This will help you export only a small portion of the clip.
Also, regarding the original issue why timeline is appearing as 7 hrs, please check other tracks as well and make sure no other media is present on Track 4 or Track 5. Sometimes, the media is not directly visible on the timeline but scrolling on different tracks give us a clearer picture.
Thanks,
