Monday will not allow items from another board (mirrored filed) to be used in Integration with Google Calendar

To keep my data organized, I used a few boards and then I link them together using “connect boards”. However, the data from connected boards do not show when I try to automate with Google Calendar.

Since I could not Do this through Monday, I tried to do it in Zappier. Then I have the same issue because the “mirror” fields don’t come up in Zapier.

Is there a solutions to this?
