Agreeing with RedFox, you do not own your videos
BUT that does not necessarily explain the low earnings.
If you are say partnered with Freedom! and you are on the standard 60/40 split you would be receiving 60% of your earnings. 4,685 monetized playbacks at £0.55 would be around £2.50. If you are on the 60/40 split and receiving 60% of the revenue that would be (£2.50/100)*60 = £1.50 which is basically what you made.
So I would say your earnings are correct. PS It doesn't seem like you have monetized any of your videos anyway so how are you making money from them
?
Hope I helped
