PSScriptPad doesn't rembember the StatusStip Settings

I have created an GUI which includes an Status Strip which holds an Progressbar.
After i have finished the GUI and Saved it, the Progressbar was visible, but after I have reopened the GUI the Progressbar was missing on the Status Strip.
I have reentered the Progressbar, and PSScriptPad created a new one with an new Objetname.

I think that could be also an Bug, because on the NAME.designer.ps1 now both Progressbars are existing.
Bit only the second one will be displayed until I open the GUI again on PSScriptPad.
