Moveset of raidbosses

I'm a little confused.
I just had a raid against an Exeggutor. It had Seed bomb as charge move.
After defeating him I cought this guy with the second throw and a golden razzberry. And surprise, it had Solar beam as charge move now.
Yesterday I noticed the same issue with a Muk. During fight it hat Gunk shot, after catching him it was Sludge wave.
Has anyone else noticed the change of moves of raidbosses after fight?

And there is another bug. I'm team Instinct, the raid was in a gym I'm in. Yellow. But after fight I didn't get the extra 2 Premier balls for gym control. Only 11 instead of 13.
