checkbox type field is doesn’t save in hubspot

Hi,

I have a problem with sending the info of a checkbox field – All the the other field work fine, but with the checkbox field I have the following problem:

I have in cf7 a checkbox – yes/no
I have created in hubspot a property with checkbox and put the 2 options
I have added the field in the tab hubspot integragtion
When someone completes the form, in the email sent by hubspot it shows me the internal name of the property like this info_events_stem_cells_consent[0]: – and the info – but when I go to contacts that property is empty.

Can you please help with this?

Thank you!
