NavBar dropdown - background blur not retracting when navigating to alternate page

Hey guys!

I’m having trouble with a template that I purchased called MUSEART

It seems that when navigating to another page via the navbar - the blur applied to the navbar dropdown fill does not retract (like the text does).
Instead the blur remains atop the content of the page & obscures its visibility almost completely. The blur eventually does retract when clicking on the hamburger menu - this is super irritating.

I would like the background blur to retreat / disappear when the navigation to another page loads (like the text does). Such that when one navigates to another page, its content is displayed completely & the blur comes into effect only when they click on the hamburger menu to navigate once again.

Any help, would be super appreciated
