I get this error when using "Update Place and Route from Reuse Template"

[Warn] : The number of components in the following group templates is inconsistent with the reuse group, and the missing components are automatically ignored:

what does this error mean, and how do i work around it?

I'm doing the following:

- create new schematic

- place Block Symbol into it

- convert to PCB. Block Symbol is messed up on PCB, components are in the wrong places.

- open "Update Place and Route from Reuse Template" dialog

   - choose the Symbol Block in the list

   - the "Updated Version" image on the right looks good.

   - "Confirm"

- Log shows the above error, nothing is changed in the PCB.
