I posted on this a week or two ago, but Logos has ignored it, so i've gone further into this. Here's why the way this resource is tagged is a problem:
Not only does using the facets in the library fail to show this resource when you own it, but it also fails to show the resource when you use the 'Store' button in library to search for it on logos using the facets as follows:
Type:Bible Commentary -> Bible:Acts
This resource simply does not show up for someone looking for a commentary on Acts. This is an error in how the 4 volume set is tagged, and needs to be fixed.
