Not sure if I interpret your colors correctly. At the
left side to me it seems you have an Nimplant within a Pimplant crossing the Nwell border (connected to the D? of the nmos, pls. see the picture below), which isn't a valid Ptap.
At the
right side it seems there is one more Pimplant partly within the Nwell (connected to the S?), which isn't a valid Ptap as well.
Valid Ptaps should have a P+diff on psub
outside - but not too far (<=10µm , in your case) from - the Nwell border, and then be connected through a contact to ME1 and to GND - not to the Source, and generally also not to the Drain of the Nmos.
