Unable to reserve sealing ordinance for Robert Barclay Welding (L5NZ-6LZ)

I am not able to reserve to the sealing to parents ordinance for this person. It says "this persons name contains invalid characters". This person has 6 siblings, 3 of which are like Robert and the same message is given about "invalid characters" in the persons name. The 3 other siblings were sealed to the parents.

I can see that Robert Barclay Welding (L5NZ-6LZ) has Sealing to Parents already reserved at 8 January 2019 by Shane Krauser. Three of Robert's siblings have their sealings already done and three siblings have their sealings reserved and shared with the temple. You can request those ordinances which were shared with the temple.

Hello @JanelleKrauser
I see you (or someone else) changed Robert's father's name so now the "Jr." is a suffix, and now the Sealing to Parent ordinance show that it has been reserved bysomeone else.
The "Jr." in the surname field was introduced during a merge.
