To confirm are you talking about swimlanes or team spaces? would love to help but need a screen shot or clarity on this

Hi @rich b101 thanks for posting in the community and @suleiry m for continuing this post! It sounds like you are trying to rename the rows of your timeline shape in Lucidspark. To do this you will need to edit the 'Assignee' section of your cards.

For more information I recommend checking out this Community Post which has a great demonstration of this feature and some details about editing the rows and card information. 

I hope this helps. Please feel free to let us know if you have any additional questions!
