I figured out how to resolve this so incase anybody has this same issue and would like what appears to be a good fix

I was able to determine that I could delete the contents of...

~/.cache/libertine-container/

~/.local/share/libertine-container/user-data/

using the the terminal 'rm -R CONTAINER-IDENTIFIER'

an also under ~/.local/share/libertine to remove the ContainerConfig.json
