Problem using UMI-tools extract

I’m learning single cell RNA data preprocessing
When I try to extract UMI-tools, I get the message “Please provide a value for this option” in the Reads in FASTQ section, and it does not open any selectable options for me.
I have attached the photo of this error to you

You have a dot character in a uploaded file name, this may be the cause. You can click the pencil (edit) icon and change the datatype to fastq. But try not to put a dot in a filename unless it is before the file extension.

Thank you. It was correct
