@dlnmadushanka It seems you have labels set to grade breaks on your sections. at the points where you have overlapping labels you probably have a sharp grade break (like a kerb or wall).
to fix this you can:
Hi,
This is something addition to what marnus said.
If you need one label at the station you can use weeding.
If you need to see both labels you can use stagger option (with stagger distance) just right side to the weeding option.
However it is best to look at your grade breaks first if this is a finished ground profile.
Thanks
