Bootstrap5 Navbar Dropdown does not drop down in specific case - bootstrap-5

Question

Using Bootstrap 5, with the navbar being a re-usable component used on many screens. The drop down menus work on all screens except for one, but for the life of me I can't see why that screen is different. JS console shows no errors, the navbar markup is identical to the one used in the other screens.
Any ideas on this are welcome.
Here's the navbar code (some data redacted for client's privacy):
<div class="bg-light">
<div class="container-fluid">
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="/">client's name</a>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse"
data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false"
aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav me-auto">
<li class="nav-item">
<a class="nav-link " href="/bkofc/">Main</a>
</li>
<li class="nav-item">
<a class="nav-link active" href="/bkofc/cases/" aria-current="page">Screen 1<span class="sr-only">
(current)</span></a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdownConfiguration" role="button"
data-bs-toggle="dropdown" aria-expanded="false">
ניהול
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdownConfiguration">
<a class="dropdown-item" href="/bkofc/branches/">config 1</a>
<a class="dropdown-item" href="/bkofc/caseTypes/">config 2</a>
<a class="dropdown-item" href="/bkofc/clients/">config 2</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="/bkofc/users/">config 3</a>
<a class="dropdown-item" href="/bkofc/inviteUser/">config 4</a>
</div>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarUserDropdown" role="button"
data-bs-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
#admin
</a>
<div class="dropdown-menu" aria-labelledby="navbarUserDropdown">
<a class="dropdown-item" href="/bkofc/users/admin/edit">my account</a>
<div class="dropdown-divider"></div>
<form class="dropdown-item" action="/bkofc/logout" method="POST">
<input type="hidden" name="csrfToken" value="..." />
<button type="submit" class="btn btn-outline-danger"> logout</button>
</form>
