Error when exporting ReconMap to SBML

When exporting the whole ReconMap to SBML from the context menu, I am getting "{"error" : "Internal server error.","reason":"com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character \u0027 \u0027 (code 32) (missing name?)\r\n at [row,col {unknown-source}]: [3,51]"}"

stack trace:
