Can not load my own track presets.

Hi All

In a project i made a folder track and with in the folder track 16 stereo group tracks
I select them all and saved it as a track preset.
In those group track are some effects , compresion ect which i always use during mixdown.
Goal is to use the track preset in new projects to save some time.
The problem is, i can not load them in a new project.
Yes the appear in the track preset list, together with steinberg preset.
I can load the cubase his own presets, but with my own presets noting happens

I can save presets of audio channels and also load in a project
Group channels wont load
