It seems like it's sort by ID, instead of by order

[pubct]

Don't know if I described it properly in the title. Do feel free to correct it.
Don't know if it's possible technically too.

On Gramps, there are IDs assigned to every person.
The issue here is that, if, for example, I input myself before my elder brother, I'll be assigned to a smaller number, compared to my elder brother.
On Gramps, that's not a problem, as I could switch the order freely, but on topola viewer however, my elder brother would be shown after me instead of the other way.
I could change the IDs, but with the number of persons, I feel that's not feasible.
