How to change the runtime from 'Flex 2.0' back to 'Flash'?

Hi Experts,

Last few month, I using SP9 for Visual Composer, the runtime is 'Flash', work nice and no problems at all.

However, after patching from SP9 to SP11, the runtime not longer have 'Flash', but only have 'Flash(Flex2.0)', and all the table layout change and have problems when sort the table.

May I know how to change the runtime back to 'Flash'? I dun wan downgrade to SP9.

Thanks and regards,
