S and D shorted after Align/abut many transistors together in Layout

DavidLou
hello experts,
we have many transistors to be abutted together, like a transistor with m=100 (yes you can use fingers but there's another question I need to ask as well). instead manually pick one by one and then abut them together, I'm trying to use Align by purposely set the spacing to get the transistors abutted together. they indeed abutted, but there are warnings about "S" of this device shorted to "D" of another which is unnecessary. 
why/how such warning comes up? how can we clean it up?
thanks a lot,
David
P.S. tried in IC6.1.5-64b.500.17, IC6.1.7-64b.500.21, etc.

    looks like I just have to flip the whole array a couple times then the tool would be able to figure them out. this seems to be my work around for now.

    It would probably be worth contacting customer support over this so that we can take a look with your specific example to see if we can spot if there's anything wrong with the setup, or whether the tool needs improvement.

    I C. doesn't have to be specific though. say put a device with m=100 (tsmc 0.18um) and align them into single row to abut together.
