Refound Passives

hello ,
In my passive tree, I have a skill's line with 2 connected skills, and I should be able to get a refund for either of those skills that are connected to their respective lines. Why can't I do it if I have refund points?
I attached a screenshot from my tree.

Your link does not work.

If this is for PoE 1, it will be easier if you click the below link and unhide your characters tab instead:

Hello,
Ty for your replay, the link is working as well now, and the chareacters tab is unhide too.

Thanks.

Characters tab is still hidden. You have to uncheck "Hide Characters tab" and then click on Update to save the setting.

The screenshot does not show enough of your passive tree. But if you can't unspec either of the circled passives, then that means that the passives shown in your screenshot are the bridge passives from the right side to the left side. If you want to remove those circled passives, you have to bridge to the left side somewhere else on your passive tree to safely remove the circled passives.
