Create new linetype in Rhino 7

I have a problem with making my own linetypes in Rhino 7.
A suggestion on how I can save new linetypes in rhino 7? It seems it does not save my settings for any editing i do.
I simply add a new linetype, give it a space for the type e.g 5,5 now is shows in document properties, then i and add it to a layer, and then it somehow resets itself as soon as I press ok.

How do i save my linetype so i can use it in a template?

This issue should be fixed in the Rhino 7.4 Service Release Candidate. If you are running Rhino 7.3, you can change the update frequency in Rhino Options > Updates and Statistics.
