Help needed with My.Scouting multiple accounts and MID

We have brother and sister scouts with multiple id’s and advancements not showing up.

Sister: Old MID is 136213104, new (current council) is 1383940, but they put the old one in scoutbook so advancements would show up. Can these now be merged and have the current council primary without advancement being lost?

Brother: Old MID is 12926688 (West LA), also 129166882?
Current Council MID 13819029 (Greater Los Angeles), but also dual with Ship in Long Beach (don’t know the MID). Would like to merge, but not sure if they paid primary with Long Beach or GLAAC.
Want to get the MID’s settled since he wants to transfer Troops within GLAAC.

Mother appears to have 2 My.Scouting accounts also. One is connected to the scouts and one is not.

Any assistance, advice would help.
This is my second request. hope someone can help me.

@LeahGrossi let us take a look

Thank you.
Looks like we have Brother taken care of. His advancements are showing up.
Zoomed with mom, and able to access her account to see both youth and put in transfer for Brother.
Sisters account, still can not see any advancements in new Troop.

Sister is fixed - brother was fixed before I looked at it

I will tell the parent to wait 24 hours and then check.
Thank you for your help.
