Error when adding 'gene' feature to 50k feature and running 'Filter, Normalize & Reduce'

[Pacomito]

3 Samples in 50k :
T_460684H_H3K27me3_50000
SA_AD1766_H3K27me3_50000
SA_AG5988_H3K27me3_50000

Samples are sparse matrices & have same names for 50kbp and feature
Adding the gene features worked fine but the bug occured when clicking on 'Filter, Normalize & Reduce' with the features 'gene' selected (fitering only features).
