txt and wildcard records

When for domain i have an TXT record and wildcard record for root domain don't works.
For example:
With record
`'domain.com:v=spf1 a mx\072mx.domain.com ~all:3600`
Record 
`+*.domain.com:x.x.x.x:86400`
Not resolves, but record
`+*.test.domain.com:x.x.x.x:86400`
Works fine.
How can i solve this issue ?
