How to remove a blank value (a floating comma) from a list?

thisRow.Pages.Year.Unique() returns a list of numbers where blank values are substituted by commas (?). I’d like to remove them.

Do you have any tip?
Thanks!

Add .Filter(CurrentValue.IsNotBlank())

thanks Paul, It works!
I thought Filter() was specific for filtering rows.
