SL: rename SLB lines to fit naming convention

Some SLB lines were found not to follow the naming convention that is used.

The summary of changes are found here:

Since this simply renames some lines, throughput should be unaffected.

The CI has broken, since it fails with the same error in master I interpret this as being from the rebase that I've just done

Having triple-checked it offline, all names are now unique and follow the naming convention (besides those which will be removed by !2347 (merged).

I therefore think it's worth doing one more CI test.
