Hi Suleiry thanks for posting in the Lucid Community! As a first step would you mind taking some time to review our Use universal canvas to streamline your workflow article from the Lucidchart Help Center to make sure we're on the same page?

If you are using the Universal canvas feature to edit your Lucidspark board in Lucidchart this should not erase your original Lucidspark board. If this is not what you are experiencing would you mind sharing a screenshot and detailed description of the issue so I can take a closer look?

Thanks in advance for your help and patience!
