While working on a command, I was testing out the radius selector to only detect certain entities, but when I try it the command doesn't work or it ignores one of the selectors.

So here was the command I was using:
/kill @e[r=3,rm=5]

But for some reason it doesn't work when I use both selectors, it only works with one.

/kill @e[r=3]
or
/kill @e[rm=5]

So if anyone knows how to fix this problem please inform me, but if it's a bug please fix it in the next update.
