Can anyone help and tell me if this is normal for ULH flights for meal selection?

we’re booked on SQ 34 In PE (SIN-SFO, on 350-ULR), and trying to do special meal selection. Kids in particular want different options for dinner vs. lunch - and we’re vegetarian so can’t even do the normal meals off the cart since those are all meat dishes (interestingly, the non-ULR 350 flight to SFO in regular Y gives a [Indian] veg option on the cart, so why they don’t even have that option for the generally higher fare/service PE is beyond me).

Daughter number 1, for example, wants a veg oriental for dinner (after departure meal) and veg Indian for lunch (before arrival). Seems that when I go to change either meal, it gives me a pop-up saying that it will override all meal selections for that pax for the flight. Ie, I can only get both meals as oriental or both as Indian, but not one for one meal and one for the other. I played around a bit, even for the ‘specific’ child meals, which specify what each meal is, only allows me to select the child veg meal for both. Seems I can select a BTC option for one meal and different special meal for the other. But in terms of specials, it seems to only allow one selection for all the meals?

is this normal? And is customer service able to resolve to our needs if I call/chat?

we were excited to try Singapore PE, but I’m already souring on the decision to do so, especially given the premium we paid to do it. How can there be so little flexibility on a multiple meal flight?

if anyone has any advice to alleviate, appreciate it. The only [subpar, for sure] solution I see, is to order different options for each pax (we are 4), and have the FAs juggle who gets what. But that means a whole lot of confusion (we already had meals screwed up in Y to DPS earlier on this trip, including being served Chicken fried rice as the ‘egg fried rice’ and my wife’s veg oriental never onboard - luckily, they were able to find an Indian veg instead). And also means that I’ll arrange so kids can be happy, and I’ll just get whatever I can scrounge up of what is not my preference.
