Service Messages displaying errors on failure

I'm using TeamCity services message to output important messages (errors and warnings) during my build. The success/failure of the build is controlled solely by the exit code of my custom build runner executable (returns a non-zero exit code for a failure). I'm noticing that on failure, only warnings are displayed and not errors. I would expect the opposite to be true (display errors and not warnings). Consider the given service messages and an exit-code of 1 (failure):

##teamcity[message text='Here is a message.' status='NORMAL']
##teamcity[message text='Here is a warning.' status='WARNING']
##teamcity[message text='Here is an error!' status='ERROR']

Produces this:

Notice the error is not displayed but warning is. Any suggestions to get errors to show up here?
