I have modified my form and saved it but my modifications don't show up

I have refreshed the form several times in my browser (mozilla firefox) but get the form in a intermediate stage of editing. The form is

https://form.jotform.com/61293215814958

 

You will see what I mean when you go down to

Personnes à contacter dans les domaines suivants (si différentes)

on my edited form, each contact person has his own e-mail and languages spoken but when I preview the form these do not show up.

We had a replication issue with our EU based servers earlier that should now be fixed.  Changes made to your form should now be properly showing in the preview. 

If they are still now showing, let us know and we will be happy to have another look.

Many thanks for the immediate response! Yes, everything looks OK now.
Cheers,
Nermin

There still may be a slight delay with updates made to forms or with newly created forms.  This can be up to 160 seconds.  Sync should be fully restored shortly.
