Predictions don't work in AppSheet?

Hello everyone, I have a question about prediction. Recently, I have a column that takes a long time to fill and I wanted to add a prediction to save time. The idea is as follows: I have a column called (Equipment name) and this column is filled either by hand or by an import. But this data is not good for my future use, so I have a second column with standard data. The column is called “Equipment type” and it is a reference to a list of standard definitions of equipment, but the list is really long. I have created a model:

But when I put the formula in my ‘type equipment’ column:

It’s not working; I get no prediction :

The idea was that when I have a non-standard equipment name like ‘motors’, the prediction understands and types ‘Motors’ in the ‘type of equipment’ column. I have also tried with a bot to execute an action, but it’s still not working.

THanks for your response, best regard
