Problems with multistep and cf7msm_prev_urls cookie with queryvar

Good morning,
first of all thanks for this awesome plugin.

We are encountering an issue with the way the previous step is stored in the cookie.

The site (well, just a landing page for now) is here: http://callmespa.com/#services
Sorry if the site is only in italian but the gist of it is:

• – user selects one of the massages from the 6 boxes
• – user gets redirected to callmespa.com/booking?type=value where value is the massage he selected from the homepage, that populates the dropdown called “tipologia del massaggio”
• – user then goes to the second step of the form and, for whatever reason, navigates away

Now, if he selects a different massage than before, the select box doesn’t get updated with the new value of the “type” var, but it retains the previous one.

I looked into the cf7msm_prev_urls cookie and I noticed that it stores the first step url with the previous query var, so I suspect this is the culprit (because this doesn’t happen in a single step form, and doesn’t happen if you navigate away while being in the first step)

Do you have a suggestion on how can I avoid this?

Quick steps to reproduce the issue:

• go to http://callmespa.com/booking/?type=Relax

– you’ll see the dropdown is correctly pre-filled

• Proceed to step 2
• Click on the header logo or navigate away
• visit http://callmespa.com/booking/?type=Ayurveda – you will see the select box still reads “Relax”

Thanks in advance for any reply
