task entry with date pushed to Planyway but not to Google Calendar

[DMB]

I have a business subscription to Trello and to Planyway.  When I add a date to a Trello card, it shows up in Planyway because the power-up is turned on, and it shows up in Google Calendar because the integration is turned on.   But when I do the same with a task entry -- add a date, it only shows up in Planyway.  It doesn't show up on Google Calendar.

Anyone have an idea why that would be?   I can't seem to find any selections I made that would lead to this outcome.

Thanks
