What you see is standard caching behaviour.

This can be verified by telling the browser to reload the page
without intermediate caches ("Shift-Reload" often do this).
When this brings up the correct result, you have a caching problem.

To avoid this problem, you must control caching.
There is a HowTo on Zope.org.
