Missing Displays after 3.0.2 Update

I am missing some of my displays when I try to schedule them. They are listed in Displays. When I go to select a display it shows three seperate listings of displays and groups each with a few in them but not all. I have tried the MYSQL commands listed in a similar thread on this problem however I get syntax error messages. It is possible that I am not typing it correctly or there is some variables I have to substitute. Any ideas greatly appreciated. As a workaround I have been creating new groups of individual displays.

Thanks.

Try running the following SQL command as in the post below:

This is the part I am having trouble with that tells me I have a syntax error

You need to copy and paste the command from the original post exactly. Note that there are backticks

`
in the command and these are not the same as single quotes or double quotes.

Copy and paste has made all the difference. I can now see all of my displays. Curiously there is still multiple headings of “Display” and “Groups” and the displays are split between two of the display headings but I am happy that at least I can now see them all.
Thanks for your help.
