I don’t know what you mean by there is no problem (code wise?).
But there certainly is display wise, in the AbhishekC image there is a blank element and I see a very similar issue.
There is no “Fill out the form below” but one opens to the right and promptly shrinks down a rounded rectangle (see my attached image). So there is no form to fill in.
That said:
I think this is down to Privacy Badger add-on on my Firefox browser as when disabled the form displays.
So AbhishekC should check if they have any privacy add-ons (esp Privacy Badger) and temporarily disable them.
