Trouble with Navigation Menu Behavior

Dear Community –

A web development company developed the site at kicteam.com and the company recently took the project over. Long before this transition we noticed that the Main navigation menu and the drop down menus, as well as the hover effects of the blue arrow :contact us” button on the left side, behave weirdly.

If you click on “About” or “Devices” and then move the mouse away and try to re-engage the drop-down menus, you find that they phase in and out and some menus will get “sticky” and overlap each other.

The company that built the site minified all the CSS (and I know this can cause issues as well), so it’s a bit difficult to narrow in on where the problem may exist.

The Contact button CSS also performs oddly. At some point, perhaps after you click on it, the button turns entirely blue. Mouse-out state should be a blue button with white “Contact Us” text. Mouse over/hover state turns the button white with blue text. Then, when you leave the button, at points it simply turns all blue (no white text).

The behavior happens across all browsers. We’ve tested in Safari, Opera, Chrome, Edge, and Firefox.

I am looking for guidance – to know if anyone has encountered this weird behavior in the menus, and perhaps point me in a troubleshooting direction, at least so I can hone in on where to look for the problem a bit faster.

This website was custom built by a web development company, using their own proprietary template system. And along the development path, looks like they minified all the JS and CSS.

If I can provide any other information, please let me know.
Thank you so much in advance. I need to save the rest of the hair on my head.
Looking forward to any insight the community can provide.
