Adds a suffix -2 to uploaded images.

This 'may' be a seperate problem to my earlier post and so I have posted it as a seperate topic though included some information from my previous post for comleteness.

I recently changed my AdobeCreative Cloud type from LR+PS+20Gb of Cloud data to just LR+1Tb of Cloud data with the intention of going completely online with my post-processing and image library. (I did have Lightroom Classic installed on my laptop but as this was no longer accessible to me after I changed CC plans I deleted it from my hard drive).

I then added images from an external drive using the 'File/Add Photos' menu option and waited for them to load into LR. Later in the session I then closed LR and disconnected the external drive.

During subsequent editing sessions I notice that the images I have worked on have been given the suffix '-2' both in LR and on my external drive and it is these suffixed images that now contain valid image with the original image name now appearing as containing 0 bytes. I have upladed an images of the files on my hard drive to show this.

Can anyone shed any light on why this may be happening?
