Timepost not sync'ing tasks with FreeAgent

I've updated a project wth new tasks and Timepost appears to update correctly i.e. no error messages, but the tasks don't appear in Timepost against the project. I have checked FreeAgent to make sure I have assigned the tasks to the correct project and it is all correct.

In an attempt to find out if it is just a problem with this one project I added a task to another project and now none of the tasks for that project appear either. In both cases there are projects that have been given manual timesheets for other tasks.

Could this be a bug in Timepost/FreeAgent?

Any help would be much appreciated
