SPF entry changed on import

I imported a text file of DNS entries for a domain, and i noted that some of the TXT entries were changed.

Eg, from:
td.site.com 3600 IN TXT v=spf1 mx a ip4:185.60.xxx.xxx ~all

the import changed it to:
"v=spf1" "mx" "a" "ip4:185.60.xxx.xxx" "~all"

is the entry valid as per the import - or do I need to go in and edit all the entries to remove the quote marks?

Thanks
