points_total does not immediately reflect the current value after the removal of gauge weight.
It can be observed that inside _remove_gauge_weight() function, it will only update points_weight of the gauge and points_sum of the gauge type, but not updating points_total:
After the operation, if gauge_relative_weight is queried by users without updating the total, it will return wrong value.
