BeatFx Quantize not working properly with CDJ-3000 on DJM-900NXS2

I’m experiencing an issue with my setup: CDJ-3000, DJM-900NXS2, and XDJ-1000, all linked via a LAN switch (or directly connected for testing). When using Beat FX on the DJM-900NXS2 and selecting the CDJ-3000 channel, the Quantize button flashes and doesn’t activate, indicating it’s not reading the proper timing. This issue does not occur with the XDJ-1000.

Here’s what I’ve tried so far:

1. Verified all devices are updated to the latest firmware.
2. Tested both direct connection and via a LAN switch.
3. Confirmed that the Link Cue works.
4. Checked that the CDJ-3000 is set as the Master Deck.
5. Verified that tracks have correct Beatgrids analyzed in Rekordbox.
6. Confirmed Quantize is enabled on the CDJ-3000 and DJM-900NXS2.

Despite these steps, the Quantize button continues to flash for the CDJ-3000 channel. Any advice?

thanks
