If I choose "No align/Hide empty buckets" option (for independent intra-pane ordering), I cannot hide split labels or set split labels orientation. In addition split labels are somehow colored. When other alignment/empty data bucket option is chosen, everything is ok. Am I doing sth wrong? Thanks for answers.
I'm afraid this is a current limitation of labelling behaviour, when using "Hide empty buckets" in combination with paning or tiling. You aren't doing anything wrong.
I've reclassified as an Idea; please vote for better labelling in this situation to be developed.
