form 7 strange issue

Hello, im having a real strange issue on a website with the form 7 plugin:

standard contact form form7 [contact-form-7 id=”1709″ title=”Contactformulier 1″] is working well on this page: https://projectpromotions.com/nieuwewebsite/wordpress/contact/

All other custom forms arent working ??
The standard form is working on every site. When I change to code of my custom forms into the standard form code its also working fine.

SO this is the code im using for https://projectpromotions.com/nieuwewebsite/wordpress/beurscatering-formulier/ :

<p>Bedrijfsnaam*
[text* your-name] </p>

<p>Aanhef*
[select* aanhef “Dhr.” “Mvr.”]</p>

<p>Naam of voorletters*
[text* your-name]</p>

<p>Achternaam*
[text* your-name] </p>

<p>Telefoon*
[tel* tel-138] </p>

<p>Mobiel
[tel mobiel] </p>

<p>Emaill*
[email* email-191] </p>

<p>Beurs locatie*
[select* beurs “Jaarbeurs Utrecht” “Rai Amsterdam” “Ahoy Rotterdam” “Brabanthallen Den Bosch” “MECC Maastricht”] </p>

<p>Beurs thema
[text beursthema]</p>

<p>Hal en standnummer
[text standnummer]</p>

<p>Beursperiode*
[text* beursperiode]</p>

<p>Beurscateringformulier*
[select* beurscatering “ja” “nee” “contact opnemen”]</p>

<p>Offerte aanvraag*
[select* offerte-aanvraag “1 hostess” “2 hostesses” “3 hostesses” “4 hostesses” “cateringpersoneel” “contact opnemen” “alleen catering” “standbouw”]

<p>Extra informatie
[textarea extra-info]</p>

<p>[submit “Verzenden”] *verplicht</p>

If I change the code, and what ever I try it isnt working. When I use the standard form code it is working but only this. Making new codes wont do a thing and really dont understand it.

Does anybody here have a clue what this might be?
