"Use with weapon set" and re-equiping on reversed weapon sets

Sequence of operations when wanting to exchange the first weaponset&gems with the second weaponset&gems renders the skill gems unusable (disabled damage stats and added maximum life to the skill)

3 snapshots:

1. using Perfect Strike with two-handed Mace on first weapon set (with it manually disabled on 2nd weapon set), alongside Ice Strike with Quarterstaff on second weapon set (with it manually disabled on 1st weapon set). Working fine.

2. Swap the two weapons' place (since I wanted to use the first weapon passives for staff and the second weapon passives for mace) to have the Quarterstaff in first weapon set and the two-handed Mace in second weapon set (thus exchanging the I weapon with the II weapon).

3. open the gem tab to try and replace their "Use with weapon set" checkboxes, and notice both skill gems are permanently unusable after disabling their respective checkbox, with both checkboxes now disabled

Added info (maybe linked?): Was using the JarnGreipr unique gloves, and was allocating weapon-relevant stats on each weaponset passive sets (+10str for mace on first, +10int +5dex for staff on second). I needed int for supports on my Ice Strike. I have tried to swap weapons, support gems, stats and the gloves around to reactivate the initial gems, with no luck.

EDIT: have since gemcutted new gems to replace them, returning to snapshot 1 with success
