Proc MI...is not a valid classification level in the ADJUSTOBS= option i

[wschuck]

Odd issue with PROC MI

roc mi data=f2a seed=20220807 nimpute=2 out=f3;
by imp1;
class trt01p oelat racegr1 region1 agegr2 serdsps1 irclgr1 trtd;
var trt01p oelat racegr1 region1 agegr2 serdsps1 irclgr1 M0 M6 M12 M18 M24 M30 M36;
monotone reg(M6 = M0 trt01p oelat racegr1 region1 agegr2 serdsps1 irclgr1);
mnar adjust( m6 / shift=.01 adjustobs=(trtd='1') );
monotone reg(M12 = M0 M6 trt01p oelat racegr1 region1 agegr2 serdsps1 irclgr1);
mnar adjust( m12 / shift=.01 adjustobs=(trtd='1') );
monotone reg(M18 = M0 M6 M12 trt01p oelat racegr1 region1 agegr2 serdsps1 irclgr1);
mnar adjust( m18 / shift=.01 adjustobs=(trtd='1') );
monotone reg(M24 = M0 M6 M12 M18 trt01p oelat racegr1 region1 agegr2 serdsps1 irclgr1);
mnar adjust( m24 / shift=.01 adjustobs=(trtd='1') );
monotone reg(M30 = M0 M6 M12 M18 m24 trt01p oelat racegr1 region1 agegr2 serdsps1 irclgr1);
mnar adjust( m30 / shift=.01 adjustobs=(trtd='1') );
monotone reg(M36 = M0 M6 M12 M18 m24 m30 trt01p oelat racegr1 region1 agegr2 serdsps1 irclgr1);
mnar adjust( m36 / shift=.01 adjustobs=(trtd='1') );
run;

SAS gives me a warning WARNING: TRTD=1 is not a valid classification level in the ADJUSTOBS= option in the MNAR statement. But this only occurs when I include M36 Monotone / MNAR rows. If they are removed no warnings.

About 23% of M36 is missing and 2% of M36 has TRTD='1'

What is the issue with the M36 call?

Thanks in advance
