Applying Child Theme conflicts with SideBar Position DropDown box

I have tried using several plugins and manually but every time I apply a child theme the Dropdown box to set the Side Position in Posts goes inactive.

My Site is: WebSite Link

So you can get a better idea of what I am referring to this is the image that shows what is supposed to show under “Sidebar Postion”.

But after a child theme is applied this is what happens after.

I am a bit unsure how to go about correcting that issue. All else seems fine. Having used one great plugin I find it is best to enque both the parent and the child style sheets to avoid a hard coded link in the header.

A view source on the object shows a few errors but I don’t think they have anything to do the issue but just in case (I would still like to figure out these errors though.):

load-scripts.php:4.3.1
The specified value “!” does not conform to the required format. The format is “#rrggbb” where rr, gg, bb are two-digit hexadecimal numbers.

As for the source code I have a BEFORE and AFTER image to look at but the difference is in:

<select name="_wp_post_template" id="post_template" class="dropdown">

Before applying any child theme the option value(s) show up like so:

<option value="tmp-1right-sidebar.php">Right sidebar</option>
<option value="tmp-3full-width.php">Full width</option>

This happen whether I use a plugin or go at it manually using the old not so great way, import, or enqueu….

Any assistance would be appreciated…
