Water and sewer drainage in same profile

Hi

I have drainage project with both sewer and Water. When I insert the sewer network into a profile I can easily move structure up or down. But when I add the water Network to the profile I cant move etheir profile and a warning window comes up saying

"Structures in profile have changed or are not displayed properly. Check the symbology assigned to structures. Use Update Drainage Profile before using this command"

When I use Update Drainage Profile the Water manholes and pipes disappear from the profile. The same warning appear if I try to move sewer manhole (the structures I added first) and it is first when the Water stuctures are gone that I can move sewer structure.

I am using PowerCivil for Denmark SS4
