(2024R1) Adding barcodes to matrix items

Hello,

We have the following scenario:

The customer sells clothes, the size and color variants were created.

Matrix items were created successfully.

Now it is necessary to create the barcodes for each item.

We select the item from ‘Matrix Items’  tab.

The system displays the inventory items screen with all fields populated

Then, when we try to create the related barcode, we can select the desired option, but when we change the pointer to the alternate ID field, the system erases all the other fields on the screen:

So, we can’t update the item.

Is there any other way to do this?

Thank you
