[Plugin: Custom Sidebars] Problem: it disappears!

Hello,

I have a problem with the Plugin: Custom Sidebars.

Here is the problem:
I make a new page, and after that I link the new Custom Sidebar that I have made with the new page; after that I add a new widget in the new custom sidebar that I have made; and AFTER I REFRESH: the widget: “Text” has disappeared… I don’t know why,really! I always SAVE IT — > everything… and it has disapperaed after that.

Please help :/
