Why captcha dow not works on Form Colapse within Chrome not incognito?

Hi Iam a facing this situation.

I am using iOS 10.11.1 and building JotForm from within iFrame on a google sites structure and see what is happening:

Captcha is under Form Colapse.

a) in Chrome Version 46.0.2490.80 (64-bit)

    a.1) when regular/logged the captcha does not shows   (I need this to work)

    a.2) when in incognito mode the captcha shows

b) in Firefox v 42.0 or Safari Version 9.0.1 (11601.2.7.2) captcha show both regular and incognito

I tyred all available captcha's in JotForm widget and only one woks, the PlayThru Capctha, but only out side of the form colapse.

Can you help me?
