Hi all, I have taken a double light switch off (to remove some cladding it was mounted on) and one wire was not connected to anything. It may have popped out of the connection when I removed the cover.
I have put it back into the connection I thought likely but now when one of the switches is acting like a master switch for the other side.

There are 2 main wires into the switch. One has a bare copper, red and black. The other just has a red and it is this red one which was unconnected.
The switch has 6 connection options with a wire link from the bottom left to the top right.

Where should the single wire go?

Thanks for your time.

A picture would really help

The single wire assuming you mean the red , could be a switch wire . if it is , does it have an earth wire ( cpc) , but as Mr white says we want more info , photos are handy.

Yeah sorry stupid of me I'll try to figure it out

The switch is like this one

And it looks like this

Looked at your images.
The twin cable ( red and black ) COULD be a feed ( red ) and switch wire black.
Turn off power at mains First ( SAFE ISOLATION ) and put red of twin in postion where you currently have single red. The single red is probaly a switch wire . A grey cable ( link ) looks to be taking a feed from the red ( twin cable ) to the black wire ( another switch wire ) . the single red could be tried in L1 opposite the common of the other red.
The earth ( BARE copper wire ) should be sleeved with earth sleeveing ( green and yellow ) and the single red should have an earth in the cable and should be sleeved green and yellow and connected with the other earth.
You could get a local registered electrician to check your connections.
