The inner screw changes the cage alignment but only on the inner position. Because the FD naturally rests on the inside stop when not under tension.

To adjust the inner limit screw (closest to the frame) , put the chain on the inner ring and biggest cog (easiest gear). Then turn the inner limit screw inwards and the FD cage will move outwards and vice versa. It should adjusted so the gap between the inner cage plate and chain should be 1mm or less.

Check the outer limit screw is not preventing the cage from moving. If so, turn it outwards nearly all the way before hand. If you don't do this first, the cage cannot travel anywhere.
