Hello to everyone!
We have focus on a strange behaviour of the "Costing Method" field of item card window.
In the inventory setup the default value of this field is "FIFO" and we keep it with that value.
Now, steps to reproduce the behaviour:
- Create a new item.
- Change the "Costing Method" to "Standard" and wait to save. The system should enable the "Standard Cost" field and disabled "Unit Cost".

- Without leave the window select again "FIFO". The window should return the original behaviour. "Standard Cost" field disabled and "Unit Cost" enabled.

- Close the window.
- Open again the item from the item list.
- Check the status of the field "Standard Cost". In theory it should be disabled but it looks enabled.

It is a strange behaviour but can only recover the normal situation if we close the browser.
Finally, we are testing with v16 of Business Central. 16.1 (Platform 16.0.12630.13457 + Application 16.1.12629.12805).
Thank you!
