In my template, I've the following code:



Upon loading the page, I get the following in the inspect element:

The inspect element shows this:



So I assuming for some reason the first hidden input that XF finds, it is replacing it with what looks like a _xfToken token value.

Any particular reason why it's behaving this way and how to avoid it?
