Agenda view with problem, todo showing date

SUMMARY

The colour and location of most todos in the main part of the agenda view are incorrect in most cases.

STEPS TO REPRODUCE
1. Create todos for previous, current and next day.  Create recurring todo starting today


OBSERVED RESULT
In the Agenda view the summary todos are displayed correctly.  In the main panel todos are listed under the day before except for overdue or recurring items.  These have the correct colour and location.  Current day todos do not match the orange shown in the summary list.  See attached screenshots.

EXPECTED RESULT
Todos shown in the the correct date column with consistent colours to the (correctly shown)summary.
