Navigation Lock could not display diffrent mode in dual-display with Opus 13

When I used Navigation Lock mode on Opus 12, it could display Thumbnails mode in main Lister and Details in another Lister. But Directory Opus 13 (Beta), it will change into the same mode in the files display if back to the parenet folder.
So, where could I modify the configure?
Thanks.

The default is to lock both sides now, but you can use this to only lock the source side:

Set FORMATLOCK=source,toggle

(left and right also work.)

Worked.
Thx.
