Well known problem :-)
The 'top 10' filter is being used besides several other filters, and Tableau uses all filters at the same time. If you want to use the 'top 10' filter as the last filter you have to put the other filters on the context.
I can see 'channel' is already defined as context filter, but if you add 'measure names' and 'bookingdatetime' also on the context (right mouse click on these filters, 'Add to Context') you will get the results we all would expect to see.
