Log file folder keeps defaulting and creating "Folder does not exist" warning

It was brought to my attention that our backups haven’t happened in a while.

I found that the Log File Folder was listed as:
/home/rei/public_html/wp-content/uploads/backwpup-000cc0-logs/

The error showed saying Folder does not exist.

So, I changed it to:
../wp-content/uploads/backwpup-000cc0-logs/

This worked and went through the following steps with a backup:
Database backup
Creates Archive (up to 56% done)

At that point I get the error
WARNING: Folder … does not exist or is not readable. (At this point the compressing file percentage continues to increase, but I get an additional warning each time)

When I look at the Log File Folder, it keeps defaulting to:

/home/rei/public_html/../wp-content/uploads/backwpup-000cc0-logs/

Can anyone tell me how to keep the Log File from defaulting and pointing to the wrong location?

Thanks in advance!
