Apparent error in date display?

I’m working on a project in the gantt view. When i select a month on the calendar (say July 1st) it is being displayed on the task bar and the gantt as 8/1 rather than 7/1. Anyone know how to fix this? Using the current version of the software and Mac IOS.
thanks in advance!

Nevermind–i figured out that i had a constraint that i hadn’t noticed that was pushing everything later.
