Based on the results at powri.com, the 5th-place finisher in Heat 1 was the 17 of Derek Holmwood; his next appearance in the results is a 13th in the Main, so it looks like he was properly advanced.
Based on the A Main results, it appears that the top 6 from the B transferred to the A. 4 from the heats, 6 from the B equals 22; Zach Daum's provisional made for a total of 23 starters, so all seems as it should be. I've never heard of any association granting a provisional at the expense of someone who's earned a spot "legitimately", and a provisional is almost always earned in some fashion; past champion, points standings, etc., and not free for anyone who doesn't make the show. That's the "provision"; making room for someone who has proven they would've gotten in of their own accord most nights, and most likely someone who was a draw by dint of his talent and/or notoriety.
