Why does "reads genomic origin" sums to only a s fraction of total reads aligned?

[Phoebe Cunningham]

Good morning,

I am having trouble interpreting the results of my RNAseq qualimap. The results say more than 120mil reads were aligned but in the "Reads genomic origin" show that the su of the read mapping to exonic, intronic and intergenic regions is less than 3mil? What are the other 117mil read mapping too?

Screenshot for clarity:

Thanks in advance for any help/clarity provided.

Best wishes,

Phoebe
