Adding a password, strange transparent box

The theme works perfectly, but I have a problem with a strange box when I add a password to a page, can you help me, is it possible to hide it ?
password: perth

Thanks you

Dear Polina,

I’m afraid that I can’t replicate the issue on my end. It might be the plugin’s issue. What will happen if you temporarily deactivate the Form Maker plugin? If it didn’t give any changes, could you please try to deactivate all non-required plugins one by one until you get it fine.

Let me know how it goes.

Warmest regards,
