Widget logic does not refresh

Hi,
I have a left sidebar and put a Text widget there. In this Widget i use Widget Logic to show some submenu pages there – it works well – the page titles are shown there.
is_page(xxx)…
If i change the page title of a shown page -> the displyed titles are not refreshed. The old title is still shown.
How can i force Widget Logic to read the new page title of a page shown with is_page()
best ahmed

The page I need help with: [log in to see the link]
