When I try and add several tags separated by spaces at the same time from the browse menu using the cmd+shift+a and I add the tags it turns it into one single tag and removes the spaces between the tags.
I should mention this is when I am pasting from the stickies app built in on a back which are actually separated by the enter button. Below is what is actually copied, the second image is what it looks like when I paste it into the tags section and the third is what it actually shows up as.
