Image Asset Does Not Update Correctly V4.4.1 Windows 10 PC

Hi,

I imported an image to the 'Your assets' section in the assets panel and used it as a pattern on a material, saved the .ssa and closed Sampler.

Not happy with the image I imported, I proceeded to make further edits to it in Photoshop and overwrite the original version of the image.

Opening the .ssa file again I noticed the image had not updated in the 3d viewport, 2d viewport, or when exporting the PNG texture. 

Right clicking on the image asset in the assets panel brings up the path where the asset is stored.... C:\Users\username\Documents\Adobe\Adobe Substance 3D Sampler\yourAssets. I then closed Sampler and overwrote the image in this folder with the newly edited one.

When I opened Sampler again I saw this still did not update the image asset.  I cleared all cache files (both textures and thumbnails), closed Sampler, reopened the file.... and STILL it was using the original version of the image (both in the viewport and exported as a PNG texture).

Then I noticed that there was also a copy of the image asset in C:\Users\username\AppData\Roaming\Adobe\Adobe Substance 3D Sampler\assetsBackup (the image had been renamed with a long string of numbers, but it was the same as the original image I imported). 
To solve this issue I had to replace this version of the file, using the long string of numbers filename that had been assigned to it.

As you can see... not the most efficient way to update an edited image asset.

Can you please answer the following:

1. What is the correct workflow for editing an image asset so that the latest edited version is seen by Sampler.

2. Why does Sampler create copies in both of the above mentioned locations?

3. When deleting an image asset from the assets panel Sampler brings up a warning saying "Note that if you delete this item from Adobe Substance 3D Sampler, you will also delete it on your hard drive."  This is quite confusing as it does not delete the original imported image, but does delete it from the folder, C:\Users\username\Documents\Adobe\Adobe Substance 3D Sampler\yourAssets. 

Can the dialogue box please be re-written to make it clear to the user.

Thanks.
