VBA hidden textbox disappears when sheet copied

Hey everyone!

New to the forum, but have used it in the past to figure out some previous VBA issues -- so I figured I'd reach out to see if anyone can help me with my current issue.

Full disclosure: I'm not the most experienced at VBA, so any dumbed down explanations will be greatly appreciated!

General idea behind my code *not actual cell references, just an explanation*:

Cell A1 has a drop down for Case 1 or Case 2
For each case I have an image and two text boxes that I am making visible/hiding depending on if case 1 or case 2 is selected.

Case 1: Image 1, TextBox 2 and TextBox 3
Case 2: Image 2, TextBox 4, Textbox 5

Right now what I have works flawlessly in the current worksheet, however, when I want to make a copy of the worksheet...some of the text boxes that should be visible now will not reappear, or will show up when they are supposed to be hidden. So example: I select Case 1 and have Image 1, TextBox 2, and TextBox 3 showing -- I now copy this sheet and go to toggle to Case 2 -- however now I have Image 2, TextBox 4, TextBox 5, and either Textbox 2 or 3 now showing OR perhaps TextBox 4 or 5 will be missing.

I've attached the spreadsheet in question -- I think you will see what I am talking about once you copy the worksheet and look at the 3D labeled images.

I assume my code is not the prettiest (as I said, totally inexperienced with VBA) -- but if there is any fix that you can think of please feel free to share!
