Reel information

[meads70]

I've bought a couple of brand new shimano beastmaster 10000 xb reels, first time using them last night, the bail arm won't stay flicked back when I'm about to cast unless i click the anti reverse then the bail arm goes right back and I'm then able to cast no problem.
Is this how the reels are meant to be used.
Hope I've explained myself lol i can't find any info online
