The delay of the inverters is miniscule compared to your 100-us period time. Those inverters will delay the phase by some fraction of ns.
Either increase the frequency of your system, or zoom in on the edges, or insert a looooong inverter chain to delay properly compared to clock frequency.
You can also use an inverter > R-C load > inverter as a delay element.

On your 1st attachment into the Delay blocks insert the Cdelay like on your last figure, between the inverters. At the top and the bottom branches too.
Or as jjx said, you can use RC too between the 2 inverters, or a long inverter chain too.
