VNAV can't make its mind up [VIDEO]

[JKawai]

Into EGJJ Rwy 8. Had to override the VNAV and use VS instead, but look, it keeps changing its mind (and adding a figure of 8 at the destination airport, hard to see here). 

Log attached. Anybody seen this before?  Cheers

It seems to be tied to a waypoint rapidly cycling between BYPASS and... Not bypass. I don't know what might actually fix it, other than removing the waypoint from the plan. Usually it's an approach waypoint that isn't going to be too much trouble without.
