This is because RWY 33L/15R is missing from MS/ASOBO data. So SID/STAR not displaying as per Missing SIDs/STARs or IAPs without runway-idents on some airports .
If you add KBWI - Baltimore/Washington International Thurgood Marshall Airport » Microsoft Flight Simulator you add RWY 33L/15R and have SID/STAR/APPR’s
