Custom indicator does not show any buffer

Hi guys,
I'm trying to load different custom indicators, but for reason no one show buffers...
Do you have any idea of what's going on?
Have no issue with other ea builders...

There are 7 buffers.
You can't see or you don't know where to look?
Btw, this indicator repaints badly.
