Monzo Flex TFL payments

Hi guys!

I’m not sure if I don’t understand this correctly or what - I just started using flex for TFL payments and it’s charging me a sum of 13.4 (even t though the breakup of payments is much less??) I’m attaching screenshots below but it’s doing this for every couple of transactions that don’t even add up to the 13.4


Isn’t it a hold for the max charge and it’ll reduce when it settles?
