Hello all,
I have a sheet I need to copy multiple times and then take advantage of the copy room feature to easily create many copies. However, despite the procedure being simple I can't seem to get it to work. To illustrate my problem I created a very simply schematic,

I then created a parent sheet and added the Repeat directive. The directive did something because the sheet then showed the stacked graphic.

However, the child sheet only shows 1 tab in the bottom of the schematic when all the tutorial say you should see multiple tabs.

Also, when I try and import changes to a PCB only one instance of the child sheet shows up. When I compile/validate the project I get no errors. However, the only clue I have gathered as to why it isn't working is an error message I get from the item manager.

I couldn't find much on this error online and I am at a loss. Repeating a sheet seems so simple in all the tutorials yet I am failing so hard. Any advice or clues on how to fix this issue would be much appreciated! Thanks,
Sami
