Text column holds value of ID

Hi all,



I have a table Actions as follow



Action ID Action

1 cutting

2 sowing

3 ripping

.. ..



At some time , on clicking the button that opens this lookup table I found some of the values of Action equal to Action ID



Action ID Action

1 1

2 sowing

3 3



What are all possible scenarios that would lead to Action column taking value of Action ID?



Many thanks!
