Describe the bug
Uhh... insert confused lenny face here. Edit mode preview =/= what is saved?!?
I dunno how this happened but the image of my odd jar is a wanderer. Look at screenshots.

To Reproduce
Steps to reproduce the behavior (e.g.):
Difficult to reproduce I think, this layout is from my 2.x GUI screen (custom GUI). Might happen elswhere too though?
I can send the layout if you tell me how to pack it so you can check if it does that for you as well.
For me,

1. Open this GUI and confirm PNG location
2. Go to Edit and look at it
3. Jar is suddenly where it should be.
4. Save and exit, jar jumps back to this place.
   Extra info, I got a rectangle above it to make it look greyed out, maybe that's an issue?

Expected behavior
Edit mode actually is the same as the saved output.

Basic Informations (please complete the following information):

• OS: Win 10 64x
• FancyMenu 3.1.0
• Forge 40.2.17
• Minecraft 1.18.2
• Active Mods ..... a LOT. https://gist.github.com/xFirefalconx/1342d4aab223943fe0fcfaf7c5c53bf8

If it's a converted layout, just remove the Image element and add it again. v2 -> v3 conversion does not has a 100% success rate.

This could be related to #724.

Fixed in FancyMenu v3.1.2!
