SIGE not to show images with .eirBckJpg extension if inside the same folder

Viktor, I observed the behavior of having two images shown of the same type inside the backend, whereas on the frontend it looks like having only one image. Unfortunately, this makes it difficult to know which file I need to edit - add description entries etc. The steps to reproduce:

1. have joomla 4.4.8 installed
2. have SIGE 4.4.3.0-PRO installed
3. have Easy Image Resizer 4.3.1.0-PRO installed
4. have a folder with jpg images
5. run EIR PRO to optimize the images inside the folder on step 4, create a backup (for example - 'dalia-fra-botanical-garden.eirBckJpg' backup of 'dalia-fra-botanical-garden.jpg')
6. Observe within the SIGE backend, the images are shown twice/on front-end once

Perhaps it reproduces with previous joomla/EIR+SIGE pro extensions as well.

Expected behavior: *.eirBckJpg not to be shown on the backend

Actual behavior: both images are shown within the backend, which makes it difficult to maintain the corresponding file changes 

It currently looks like expected behavior, although it will be better to have only one image shown rather than the same twice or more. Screenshot references attached.
