What the plot probably means is that those are transcripts annotated in RefSeq, but when it comes to RefSeq_antisense, it might mean that those are antisense transcripts of RefSeq annotated transcripts, or that are RefSeq annotated antisense transcripts, so not entirely obvious. Check the tool/docs for better suggestions.
Thank you

WDR33

WDR33
is protein coding or coding for a small RNA etc?you can do is search NCBI to figure out what terms might mean
