The problem here is that using data validation can lead to circular references (which prevent it working).Here's a solution which avoids that by using a helper column, based on the method shown an article elsewhere: How To Hide Previously Used Items In Dropdown List?
In the attached file, I've used that technique but put the helper columns in hidden columns I:K. The data validation in column B is based on that in K (and the list will reduce as the options are selected).
Currently it offers choices PTO1 to PTO10 but I leave it to you to make reduced options if needed.
Hope this helps.
