Losing skills when adding after splice

After splicing, when I go into add skills, the last one says
"You don't have that skill in your skill bank. ^___^"
Not sure if Vicious Stab being picked twice at first makes a difference.
Even though the monster knows Vicious Stab it still appears first on the list and when I pick it it reappears again. But other monsters are just fine in the same situation.
Monster 8230 lost Sturdy before and is about to lose Stone Skin.
Monster 8600 is about to lose Sturdy.
I'll see what happens when I evolve 8600 and the skill bank resets.
All skills were there except Sturdy.
Removed links not to mess with their new evolution.

#7373 just lost 12 to 15 skills.
It was the last splice, the fifth. All 4 before were fine, all doing the same thing had no problems.

Hey mogu/crimson. Sorry to see you lost some skills, mail me on monbre or just tell me what they were here and I'll try to save you. I'll make a note of losing skills via splice... unfortunately I'm totally swamped with other work at the moment!

Hey Vael, is it mean to say glad you're swamped with work and busy?
#8230 lost stoneskin and sturdy
#8600 lost sturdy
it's not a big deal

This is an estimation going by what was learned and others cause not sure.
#7373 lost Fall and deliver, Refreshing Blows, Critical Mastery, Omen's Fury, Lucky, Stochastic Poison (easy to get), Demonic Flesh, Mokal's Cloak, Fire Inside, Holy Frost Resistance, and Undefilable
Don't recall if it had Eagle's Eye, Stoneskin, and Sturdy or Aura of Hardiness, Aura of Verility, and Aura of Blockiness

This has sat on my list for over a month... I'm sorry, MonBre's such a mess internally that I can't justify spending thirty minutes figuring this out. I'll make it up to you in MonBre 2.

And I won't remove it from the MonBre ToDo list.

No prob
