1/2 day increments leaving the second half of the day free

I was messing with date structure and somehow the date went to 2030 and a bunch of settings around start date adjusted on a pile of line items. Most likely a weird bug since I didn’t do much to make this happen.

Anyways one really weird things happened. All my 1/2 day effort for tasks now use a full day. on the gantt chart it shows them as 1/2 day but then the PM part of the project shows as blank. The next task should start immediately in the second half of the day. Any idea how this happened and where i can look to fix this?

Resolved! I changed the project timing to “Exact”.
