Hi,
Stations selected to run under the same Start Time will run consecutively back to back.
Start Times that are back to back in a single program, need to have a 1 minute difference between them (see manual Section 5 page 10 Note at end of section).
This assumes the same program is being used, this does not apply if the Start Times are in different programs.
Is this perhaps the issue you are seeing?
If you want two (or more) stations to run consecutively, simply put them under one Start Time and set the time for each to run. (Double check that your check boxes are selected for the correct Start Time and enabled, etc)
Below are a couple of example screen shots. The first shows 2 stations configured to run back to back under 1 Start time with calculated end time of 10:30 AM. The second world do the same function (not sure why one would want to do this specifically) but requires the 1 minute offset between Start Times resulting in a calculated end time of 10:36.
