R30837 GL date in F0911.

Hi,         on 23/04/20, I ran Frozen cost update -R30835 and turn on WIP Revaluation in processing option #5 tab process and specific GL date = 20/03/20 in GL tab. After R30835 done in the submitjob have job of R30834 with GL date 20/03/20 as processing option behind R30835 and job of R30837 create batch date as 20/03/20. I review F0911 by batch number from R30834 I see that gl date is 20/03/20 as processing option. I review F0911 by batch number which was created by R30837 ,I see that GL date is default as system date(23/04/20).         I'm not sure GL
