Rebalance channel selection issue

I have two incoming 2M channels from the same node with an alias. The issue is that when I try to rebalance one of the channels the funds arrive in the other channel which is already balanced. I tried in Thunderhub by selecting the channel which needs balancing but the funds go to the wrong channel.

I also tried the rebalance-lnd script which shows different channel ID’s for the same alias but even by copy/paste the correct ID the funds arrive in the already balanced channel.

Is there a way to force the funds to go to the selected unbalanced channel?

Sincere advice: don’t bother too much with this obsession of rebalancing. You are just wasting your sats and time.
