Empty Pop-up Window Remaining on Screen After Cookie Policy Closure

"Simple Cookie Compliance" module simultaneously on my website. When the page initially loads, the "Splash Block" module displays a pop-up screen which I close (step1). Then, on all pages of my website, there is a persistent Cookie notice at the bottom, which I close by clicking the "OK" button (step2). - The real issue arises from this point! - After closing the cookie policy (step3), the "Splash Block" module comes into play and presents an empty pop-up window on the screen.

When examining the CSS changes, I noticed the following modifications:

(step1)

<div class="splash-block-overlay" style="display: none;"></div>
<div class="splash-block-modal" style="width: 520px; height: auto; top: 450.5px; left: 683.5px; display: none;">

(step3)

<div class="splash-block-overlay" style="display: block;"></div>
<div class="splash-block-modal" style="width: 520px; height: auto; top: 450.5px; left: 683.5px; display: block;">

As a result, when I accept the Cookie, the JavaScript triggers the -"style="display: none;"- within the (.splash-block-overlay) and (.splash-block-modal) classes. I think it's causing a js conflict by the Simple Cookie module.
What could be the solution?

How can I fix this issue?
Thank you in advance for your assistance.
