Its only a small subset of the STL code that can be viewed as LAD.
There are limitations and requirements.
One limitation is that the number of instructions can fit horisontally on the screen.
One requirement is that all unused "pins" (in Timers for example) are set to "NOP 0".
There are other factors that can inhibit the ability to view the code in LAD.
It is best to create the rungs in LAD, and not edit in STL if you want to view in LAD at a later time.
If some code was created in STL, then it is highly unlikely that it can be viewed in LAD.
The same goes for FBD vs. STL.
