Items couldnt be taken up snd vanish very fast

Hi, 

 

I play on a Honor Play the latest beta build and sometimes items and xp orbs couldnt be taken up. they appear on the ground normally but vanish alot faster when this bug occurs ( approx. 30 sec)

So far I noticed this bug with a diamond sword, a diamond axe i threw out of my inventory and with xp orbs.
