Something to be concerned about?

While running upgrade scripts from 10.13.66-15 and upwards, see the following and wonder if it’s something to be concerned about:

No Packages marked for Update
/usr/local/sbin/amportal: line 44: export: -': not a valid identifier /var/lib/asterisk/bin/freepbx_engine: line 119: export:-’: not a valid identifier
/usr/local/sbin/amportal: line 44: export: -': not a valid identifier /var/lib/asterisk/bin/freepbx_engine: line 119: export:-’: not a valid identifier

The update completes normally.

Thanks.
