Signals Notebook: Not found error messages received when working with specific monomers in the HELM Editor

Description: When pasting a HELM string using the HELM Editor a 'Monomers [] were not found' error message will be displayed, yet the monomer exists and is not deprecated. The network log will show 404 errors when attempting to load the monomer. This prevents the structures from building correctly.

Solution: For each affected record listed in the error message navigate to the monomer in the HELM library then 'Deprecate' the monomer then 'Restore' the monomer. If problems persist for specific monomers after this process, contact support for further assistance.
