CDJ2000NXS2 - Performance mode glitch

HI Team,

Just noticed something weird.

Using DJM900NXS2 + 2 x CDJ2000NXS2 - RB 5.4.3. - WIN10 on a decent clean Laptop

All firmware to latest version today. CDJ 1.84 DJM 2.05

Using performance mode - I have the CDJs running via ethernet. DJM plugged via USB.

The issue is thus. When using vinyl control mode on the CDJ - if the track is spun back to the very first section of the track there is a very noticeable delay on the release time. It only sticks to the very start of the track - otherwise it is as responsive as usual!

I've had a look through setting - CDJ are on single play, and the "play through list of songs" on the controller section is unchecked, so I do not think that it is trying to load the previous track (I've had this before, and it does not like it!!)

Anyway - I can send a video if you cannot make this fault appear.
