sender field in outlook shows not the full name

Hi guys,

The contact form is working like a sharm, but i have an issue i can’t resolve.

So this is the tag i use in the form:
[text* your-name size:30 maxlength:60 class:form-control]

In the mail tab i have the following
[your-name]<[email protected]>

When i receive yourname in de senders label of outlook i’ll get something like this:
FirstName LastNam

In the body I get the full name with the same tag [your-name]
FirstName LastName

As you can see the last letter of LastName (e), is not shown in sender.
Any help is much appreciated
