Error syncing

[Igor-just-igor]

Hi. I'm experiencing this error and don't know how to solve it. It's stopping the app from syncing.

My app is a modified version of the Kanban template.  The Status column is Enum and I changed the possible values, 'To-Do' isn't in the list anymore. I've made this change many updates ago and it had been going fine for weeks 

I don't know what change have I made that caused something in the app to try to insert 'To-do' back everytime I try to add a row (according to the error text). The error shows up at initialization, not when I manually add a new Task to the table.

I did check the source data and there was no 'To-Do' value anywhere.

Any help? Thanks!
