Sometimes I'm experiencing similar issues. I'm not sure but to me it 
seems these are problems caused by the webbrowser and/or the webbrowser 
cache and/or Plack. Usually they can be solved by clearing the 
webbrowser's cache (e. g. in Mozilla Firefox the cache can be cleared by 
pressing CTRL+F5).

If the problem persists I tend to restart Koha (including Plack) using 
the following command:

$ sudo koha-common restart

However, these are just hints, no solutions. Since Koha works with 
Webserver (Apache), Plack, Memcached, Webbrowser-Cache, Javascript... it 
all has become a little intransparent to me... esepecially if more than 
one person uses the same login from different machines etc.

Maybe it's the same problem because you're using the same webbrowser 
when accessing productive and test installation?

Maybe this helps (a little)
