Errors and not saving all data to fields

It is simple.

Just add a number field and that's it.
This error appears when saving the new node also when editing.

And very important:

That the error is repeated for each field number of the custom_field in the same content type.

I also saw a strange thing.

When you create a new content type and save it, the keys appear and not the values. But if you go to Manage Presentation and simply change the presentation to key in any number field and save, all the number fields show the value and the one you changed shows the key, and then you put it back to value, everything is normal. You have to repeat this matter if you have added another number field, so that all the number fields present the values ​​and not the keys.

These errors appear only the first time when creating a new content type. Then they no longer appear.

Create a new content type, add a custom_field of number format.

Create the first one, and you will see the error, edit it and the error appears. But the following new ones created and edited no longer appear.

Gracias.

I confirm all working.

Thanks for this module.
