Can't remove margin-botton: 25px in Offcanvas icon

Hi,
I have no idea why the Offcanvas icon was added margin-bottom 25px on frontpage.
When I disable the Custom Module (ID205),the Offcanvas icon normal.
Can you please have a check for us?

There maybe style for the btn class, you can override by this:

@media (max-width: 767.98px){.t4-offcanvas-toggle {margin-bottom: 0px;}}
