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
