I would like to merge three (replicate) bam files in a collection/list into a single bam file.

When I try to do this with Samtools merge, I can only select the collection but not individual bam files. And if I select the collection in which there are the bam files I see the following message.
Is there a way to see what these data 189, data 187, and data 188 are, to know what I’m merging?
Thank you!
