If you want to email me the files, I will try importing here and see if I can reproduce. I don't think it should be an issue.While on the topic of this, I think I found a hang-up. Either I hit the limit of ID's able to be imported, or it doesnt allow duplicate ID's. Each time it will import all of the ID's from one of my CSV's but then it gets partway through the second and freezes. The 2 systems have an ISSI link and radios frequently pop up on talkgroups on either system, so i just copied the entire list and gave it the corresponding names. For reference I have around 6000 Ids in each file.
