Web form Hidden Field Showing Unique Values

Hi Zoho Community,

My team and I are experiencing something odd with our web forms. To improve our web analytics we have hidden fields in our web forms that tell us what web form the lead fills out. This field and value

is pre-defined and hidden as seen below.

Now what we are noticing is that some of the leads we are getting are successfully being converted into our lead module, but the values for property Website Web Form are not familiar. For example in the illustration below.

Those Website Web form values with special characters are not even available pre-defined options, although some of the leads we are getting are coming in with those values.

Anyone else experiencing this, something similar and can provide any insight at all?

Thanks in advance for reading.

Sincerely,

TM Operations
