Premiere Pro is clipping the last second of my project.

Before today i've never had this problem. I recently got a new computer and have been editing from it for a couple weeks now but for some reason today all of a sudden on this sepcific project it doesn't match the time on both sides no matter what i try unless i move the bar to the end of the project and even then the screen doesn't go to black like it usually does when i export a full sequence. I'm not sure how to exactly explain this but basically it clips the last second out on the export menu and it's causing my export time to be really long. Usaually i can export a 40 minute video in under an hour but for this 39 minute project it's saying that it'll take 10 hours to export.. i'll insert a picture.

by any chance are your sources from a screen recording or shot on a smart phone?  If so, the issue is probably that they have a variable frame rate which is problematic for Premiere. 

use mediainfo to determine whether your source is variable or constant frame rate

if it's variable use handbrake to convert to constant frame rate

and here's a tutorial on how to use handbrake

Thanks for responding i think the problem was that my new computers hard drive can't process the video right. I moved the project to my sisters laptop and was able to export it in an hour.
