Chinese bank "o o" rendering error

I have noticed that, when using Chiyu and Shian, rendering two ‘o’ phenomes next to each other like the image creates a pause in between notes.

Have you tried making the second note a “-” to continue the first note?

Or were you wanting each note to be pronounced individually?

Have you tried wo wo?

“wo wo” and “o -” are functional. I was more intending to report a problem than to find a workaround.
