MS Project Calendar Tasks Not Correct Length

I am building a schedule for a project and am having an issue with the calendar view. 

I have a series of meetings that are all 2 hours in duration, but when shown in calendar view, the two that fall between the 3rd and 6th working hour of each day are much shorter than the others. See the example below;

Is there a way to fix this so they all occupy 2h worth of space in the calendar view?

Thanks
