MH won't accept sync time for data sync to CRM

MH won't accept sync time for data sync to CRM

Having run out of allowed immediate syncs, I am now trying to setup daily syncs in MH to pull data from CRM Leads Views.

When I first set a sync up, the default time is 0500PM (screen-162). I presume that's beause 0500PM was close to the current time. I chnage that to 0900PM (screen-163 and 164). This seems to be accepted. But when I complete the setup (screen-165) then go back in to check, I find that it's been set back to 0500PM (screen-166).

This become a bigger problem when I try to setup subsequent syncs because it tells me I already have a sync scheduled for 0945PM (screen-168). I don't. But, if MH is ingoring the sync times I'm setting, it's probably trying to setup 2 syncs at 0600PM. 

What can I do to make MH actually listen to what I'm telling it. I've tried clearing browser cache.
