Forum .LRN Q&A: Changing description in a class/community or subgroup is'nt reflected everywhere

When using "Edit Group Properties" and changing the description only dotlrn_communities_all is updated, not
static_portal_content. The later one is used when showing the content (description) with the static-portlet package.

I found a code-segment that might be possible to use:
    -portal_id $portal_id \
    -content_id $content_id \
    -pretty_name $pretty_name \
    -content $description

but I don't know how to find the correct content_id.

Appreciate any help in solving this, thanks.

ps: using dotlrn-head.
