My wallet keeps going out of sync after a little while 30 mins - 4 hours as if it is trying to get onto a much bigger chain ?

It will start off fine and stake saying the chain is about 4500 blocks then after a while it goes out of sync saying it is trying to sync with 100000 blocks or something to that amount I will get a screenshot next time if this doesnt make sense.

Anyone else having this problem or just me I have emptied addnodes deleted peers.dat and resynced a few times but this error keep happening so I am unable to find a pos block.

Any help appreciated thanks
