Files not visible in Demultiplex Pipeline

Hi All,
I am using flowBio to analyse my CLIP data. However I am currently having problems with a very early step - After uploading my data, it does not show up when I go to demultiplex the files. I have tried this will files that I have previously succesfully analysed using the flowbio pathway so dont think its an intrinsic problem to the data.
Any thoughts much appreciated!

Just for anyone coming here in the future, this issue was resolved.
