The program applied the lateral stability factor KL for glulam from O86 6.5.6.4 to structural composite lumber, whereas the O86 13.3.2.7 says to use the sawn lumber clause 5.5.4.2. Note that 5.5.4.2 specifies use of 6.5.6.4 if a set of support conditions are not met, however for SCL you were not afforded the opportunity to indicate via the design setting that these conditions are met and that KL =1, as you are for sawn lumber. Now that setting applies to both sawn lumber and SCL, and it indicates so in the checkbox text.
