It seems you had 2 blocks staking one big and one small and the big block staked 2 hours earlier but they should merge now that small one staked.
Do you maybe know how to use coincontrol?
Best is to confirm in coincontrol that there is only one block because it can sometimes happen there are more like when you send new coins to the wallet or after it staked it sometimes put them in a new block and you need to merge them manually to get the best PIR. You can merge them by sending the second block(s) (if it,s a different adres) or all blocks to yourself.
Also a tip when coincontrol is active you have in send coins page a option to fill in a custom change adres. Put there your adres so when there is change it sends them to the correct adres
