Error publishing lane data as custom message

I am trying to publish XY lane points in world coordinates as a custom ros message. No problem adding the custom message to matlab.I can see it in rosmsg list. The error occurs in data assignment. I get the following error

'A signal can be assigned only once, but the assigned bus signal 'Xleft' fully covers the assigned signal 'Xleft.Data_SL_Info.CurrentLength' in block 'LKA0110/Subsystem/Bus Assignment1'

I could not find a suitable explanation on what this error means. Has anyone encountered this before?

Thank you
