Help me understand why this resulted in a loss? Spread Betting with Limit & Stop - BUY Position increased in value but still made a loss?

[MarcusClifford]

Hi, I'm after some guidance as to why a spread bet position and close resulted in a loss for me.

I placed a BUY order for NIO at £1 per point at a price of 4551  I set a Stop at 4497.9 and a Limit at 4617.25 at time 20:11 UK Time

The price of NIO increased, as can be seen in the graph - this is good I thought - indeed the positions showed a profit.

The price increased and hit the value I specified in the Limit and the system automatically closed my position - that is good and what I wanted. This happened at 21:02

My problem is this then says that it closed at 4497.9 at 21:02 when the price was actually 4617 which was the value I set as my Stop Loss position even though the price was now 4617 - as can be seen on the graph.

I assume I have misunderstood something, but I don't get why the close price was the stop value rather than the Limit value when the price hit the limit and I should have made a profit (as it was a BUY and the price went up). 

Can someone explain what I got wrong here?

I've attached a picture showing what I think is the relevant information.
