DFPlayer AD-key doesn't seem to work?

Hi all,
I have four DFPlayer Mini modules (SKU: DFR0299).
I cannot get the "AD KEY" mode to work despite following the instructions in the wiki/datasheet exactly.
I know it isn't the mp3 files because I can navigate them using next/prev (IO1/IO2).
The only one that works is "segment 1" by grounding ADKEY1.
"Segment 5" "segment 12" and "segment 13" all did not work when connected as shown here.
Has anyone successfully used this mode?

I am sorry that I have not played the mini with ADkey module. I will do a test and any progress will be updated here.
