Why does auto advance stop working on convert mode after writing for a while?

Edit Subject

In the screen shot below you can see that the gray auto advance area
isn't on the right side by where I just wrote the "a".

I have to manually click the space button or the words just converted to be able to keep writing.

I spoke with Ben from support and he suggested I turn on the Auto Feed feature.

The problem is that the Auto feed (for stroke) feature does not do anything in the convert mode. It controls how quickly the software assumes you've written a word (stroked/handwritten, not converted) so as to automatically split it from the next handwritten word.

Can you guys introduce an optional feature that automatically locks in the the previously converted words instead of requiring it to be done manually?

This is a dealbreaker for me.
