PROC PHREG plots(overlay cl): Graph does not have confidence interval bands

Hi, everyone

The origin issue was posted at this thread in the reply section update (https://communities.sas.com/t5/Statistical-Procedures/How-to-plot-cumulative-hazard-graph-with-95-CI-rather-than-95-CL/m-p/935295#M46621)

My code lines are

proc phreg data = cox_raw plots(overlay cl) = cumhaz;
class genderC(ref = '0') AF(ref = '0') Hypertension(ref = '0') CHF(ref = '0') akiC(ref = '0')
ddiC(ref = '0') indicationC(ref = '0') CYP2C9code(ref = '0') VKORC1Code(ref = '0') Warfarin_History(ref = '0');
model timeToFirstInrAttain*firstInrAttain(0) = bsa ageY genderC AF Hypertension CHF 
serumalb akiC ddiC indicationC CYP2C9code VKORC1code Warfarin_History / rl=wald;
baseline covariates = predict_cox;
run;

If the plots() only have cl option (i.e., plots(cl)), there is a confidence limit band in the graph. But it is not when the plots have both overlay and cl options (i.e., plots(overlay cl)).

Your feedback is much appreciated!

Tom
