for me it shows the installed libraries (W10, P4.3).
Did you maybe changed your sketch folder or similar which leads to an empty libraries folder for the new directory ?
It can see libraries status checkmarks when I install Android mode!
When I remove Android mode it does not show installed libraries.
Be sure to restart Processing if testing this.
I confirmed this on the two PCs I have with W10.
I did remove all Processing related files on the one PC when testing.
