Selecting multiple configurations from the Image Source selecting window and Target Configuration

[AAndrisa]

Environment:
OS: Windows
SW Version: Version: v1.0.0-rc3

In this scenario we test the update values for the Image Source and Target Configuration. After selecting multiple times different images there is displaayed the last configurations plus the current one (same with 2 SD cards and with write protection)
When navigate within Target configuration selection and going back, not selecting one configuration all of them appear on the screen after just closing the navigate window.

Steps to reproduce:

1. Click on "Image Source (Unconfigured)."
2. Select "ADI Kuiper Linux" from the list.
3. Click again on the Image Source and select “ADI Kuiper Linux” and then just close de window, the field will reset to Image Source (Unconfigured)
4. Click again on Image Source and complete the selecting process for Kuiper Image, after that both selections, the current one and the old one appears
5. After that on the selecting Target Configuration process just navigate through the windows and then close the window, many will appear set on the Target button.

Expected behavior:
Only the selected value should be displayed on “Image Source”, or the field should be reset to empty, or previous value (if there was one)

Behavior exists also on macOS and Ubuntu. Previous actions are retained.
An alternative way to replicate issue for selecting Image Source:

1. Select storage
2. Select an image in the image source
3. Click "WRITE"
4. Wait to finish, do not close imager
5. After writing, click continue and select again a storage
6. Select again a source
7. Notice that the previous selection is retained
   This also happens when the action selected is "ERASE".
