How to edit Thumbnail showing wrong image?

[lorenzo perez]

Greetings Atlassians, 

Our company recently rebranded itself so all of our content in confluence is being replaced. I have a file that was updated and when I load that file (excel file) into Confluence, the preview of the file shows the previous brand view? 

When I open the file that old brand does not exist in the file so I'm at a loss why it shows in the preview. Old image is Grey & Yellow Theme, New Image is White & Blue Theme

I have attempted to delete, rename, and reload with the same results. 

If anyone has an idea of what the next steps should be or a viable solution, I would be eternally grateful. 

Lo

Not sure what can be triggering this weird behaviour but let's try the following:

You delete both files the one with the old info and the one with the new info.

Try to clear your browser cache /history then add the attachment with the new info and see what will happen.

Also did you try different browser to see if it will happen?

Best,
