podtree number / string bug

In podtree if a number is overwritten with a string it remains as a string, even if the user re-enters a number. For example in /appdata/system/code.pod change selcol to "yellow" then back to 10. 10 remains as a string. And results in the code highlighting to go awry (see image) until code.pod is deleted and reset by app.

This is minor, but I was hoping to offload all app settings to podtree,(ie stay in picotron os / app world) without recreating a settings pane, or having to save back to a pod from the app.
