static front page not showing wp form?

Hi,
I’m happy with Customizr overall but still have some problems.

I’m using static page for front page and I have contact form there if not linked to front page – but if I link it to front page the form is not showed.
Also building page with page builders (I tried couple of differnet ones) doesn’t work for static front page.
Testsite: https://pakrisaared.ee/ver3/ (in estonian only, but language is not important).

The form thing is really important, probably need to add some code?
I’ve already using child theme.
