Hey Rose -
Thanks for reaching out, but to be honest I've never heard of or seen anything like that before. My guess is that it has something to d with your browser's spell check settings, but it's hard to say without seeing it directly.
If possible, please take a screen shot and send it to me directly at j@getvela.com.
This will allow me to identify the issue and more importantly determine how to resolve it.
Thanks,
Justin
