Rekordbox 6.6.11 missing waveforms in old library,

Rekordbox 6.6.11 missing waveforms in old library,

in new library (for opus Quad) see all the waveforms.

This happend when update to 6.6.11, new uploaded tracks in playlist rekordbox (with the waveform) after synchronize missing waveform on usb, only in old library.

Tested on 2 windows laptops, also with a new usb stick.

So I'm sure it's a bug.

When I turn the device library plus (opus quad) off in rekordbox, and synchronize a new usb, I've all the waveforms (but only old library :-(

Please helpppppppp!

Never had problems with rekordbox
