Adoption Name Change: Donation to Missionary

We adopted a 20 year old who whose name wasn't changed when he submitted mission papers and was called on a mission using his previous name, we have since changed his name and everything has been changed with the missionary department and our local membership clerk has changed his name and it shows up correctly on LDS Tools and in the membership record, but when I try to make the first of many donations to his Mission fund, it is still showing him there as his old name. I contacted the missionary department, but they said it was a membership issue and to check with my membership clerk. I spoke with him yesterday and he can't find any additional places to change the name. Can someone help?

The clerk is probably going to have to contact the missionary department and/or the finance department. I think the problem is the name is pulled from the membership records, but isn't updated from them. It's quite rare for someone to have their name changed during the calling process. Most likely, someone (at headquarters) is going to have to go in manually to change it.
