Web monitoring variables are not working after Update to 3.2.1

Up to yesterday we used 3.0.x version. We have configured a lot of Web-Monitoring scenarios. Up to now we used a macro for domain configuration:

{domain}=http://www.myshop.com

and in the Steps we used that macro for the URLs:

{domain}/firstpage.html
{domain}/secondpage.html
and so on ...

So now after the update to 3.2.1 all Web-Monintoring scenarios do not work any longer. Error message is: "Step "Startpage" [1 of 4] failed: Couldn't resolve host name: Could not resolve host: {domain}"

So it looks as if the macro is not recognized any longer. I did replace the macro in the steps with the real domain name - and then it works. But as we do have up to hundred and more of such checks I would be thankful if I would not have to change alle the steps manually ... :-o

Can you help?
