iCal not showing travel time on iPhone

Recently, I've set my work Mac to send me iCal invites for my work schedual. I've set them to have my work address and travel time from my home address, but they don't show all the information when my phone is invited. My iCal on the work mac shows all the information, but sometimes wont let me add travel time to events period.

Have we heard any fixes on these issues?
