Tried both removing and pasting in a current Tipsheader line. Did not resolve the problem.
Tested it with 6.6.0.81015 wich I have running on the side, and it imported without problems.
Maybe I will just create the config manually.
Read this, but not certain it has something to do with it:
Users should be aware that context server actions that were defined prior to ClearPass 6.7.0 cannot be imported to a 6.7.x version by using the Endpoint Context Servers list’s Import or Export options, nor by any other import action that includes context server actions (for example, from Services with context server actions included).
