Using FixedCloumns, div.dtfc-right-top-blocker appears in top corner of my page

Using the following code to use datatables:

<link rel="stylesheet" type="text/css" href=""/>
<script type="text/javascript" src=""></script>

Using Bootstrap 5 I am initialising the table using the DOM attributes as below:

 <table class="table align-middle dtselect nowrap table-hover" data-page-length='10' data-fixed-columns='{"left":2,"right":1}' width="100%">

What I am finding is that a new element is created on my page that I am not in control of and is positioned in my navbar as a white line covering up some text in my navigation as you can see from this image a line covering up the Help button:
White line covering Help text

When inspecting the element, this is what I find at the very end of the page.

<div class="dtfc-right-top-blocker" style="inset: 0px 0px 0px 1449.67px; display: block; position: absolute; width: 1px; height: 42.3125px; z-index: 1;"></div>

It appears that the element is being added to the body of the page rather than the table container. The table appears to display correctly and function as I would expect. The line disappears when I remove the data-fixed-columns='{"left":2,"right":1}' code on the table element.

Has anyone else had a similar issue or know how to remedy this?

Many thanks,
