DataSource Unavailable

For InfoObject 0CRM_USSTAT, I had two datasources available, 0CRM_USSTAT_TXT, which I was using, and 0CRM_USERSTATUS_TEXT, which I now want to use instead.

I have deleted the source system assignment and I am now trying to use the other DataSource. However, only 0CRM_USSTAT_TXT is available now. I have activated the 0CRM_USERSTATUS_TEXT datasource in the CRM system and replicated the datasources in BW, but when I try and assign the datasource to my infoobject only 0CRM_USSTAT_TXT is available.

Any thoughts on what I might be doing wrong?
