A350 and time skip

Using time skip in the a350 seems to break the auto pilot, first it removed the green line on the screen but kept it on the tablet and then it just started turning left and went out of managed mode, did i do something wrong? or is this a bug of some sort?

Thanks

I was flying from ESSA-VTBS. The route on the navigation display was gone like i never had a route (picture of the line i was thinking about, but it kept flying it for a bit. tried this again and it happened on the a380 too

Only happened after like the 3rd time skip
