I just did the highest level bounty available from the steel path selection for Cavia, which says it should give 7,500 standing, but I only got 2,000 standing from it. I then tried the highest level bounty available from the normal selection instead, which says it should give 5,000 standing, but I only got 1,000 from it.
I have plenty of daily standing left, so I don't know why they're giving this little.
