Quick Q as not experienced this before and can't find an answer.

I have a CE, Valencia - Heathrow - Manchester booking I no longer need. None refundable of course but I can change the date and I might be able to link it in with some other travel rather than chuck the 80TPs away.

When I've changed two sector tickets before it's the highest change fee that has applied and they just charged that plus any fare difference, however on this occasion I have 50 euro fee listed on the Valencia to LHR leg T&Cs (£30) and £100 for the LHR to Manchester T&Cs and they seem to be adding it together to give a cummlative total change fee, before fare diff, of £130.
Has this changed, have I just missed it before or is it wrong and I should call Gold line to action Change.
