Work around
Resources included in this filter, click on the import computer list and add the csv, click OK
Resources included should say number of devices in csv
Click on the list of devices in the “resources included in this filter”, click on Ok when the devices list comes up
Then click on save and the devices will remain in the filter membership list
I about 75% sure in 8.0 you just did the first steps and all of the devices stayed in the filter and since we went to 8.1 you have to go into the resources included to get it to stay now, anyone confirm that?
