Hello all,

I have a simple dropdown with a query providing a two column dataset for the data. If the selection mode is set to `Strict`, every time I open the screen in the Designer it shows the `No Selection Label`: `<Select One>`, even though I set the `No Selection Value` to a valid number in the dataset.

If I change the selection mode to `Lenient`, then I get the correct `Selected Value` and `Label`. Going back and forth between `Strict` and `Lenient` did not produce any changes in the `Selected Value`, it stayed the same number while switching between modes.

**So, what is going to between these two modes?** The docs say that `Strict` requires the value to be in the dataset, which it is.

From the [docs](https://docs.inductiveautomation.com/docs/8.1/appendix/components/vision-components/input/dropdown-list):

- **Strict** : Selected values must always correlate to an option in the list defined by the Data property. If an invalid selection is set (via a binding or a script), the selection will be set to the values defined by the No Selection properties. If the Data property is set to a list that does not contain the current selection, the current selection will be reset to the No Selection values.

Does this mean you've added -1 to the value column of the dataset or you've changed the default -1 to some other number? Also, is column 0 of the dataset an integer datatype?

Column 0 is indeed an integer, column 1 is string. All integer values are positive, starting with 1.
