Problem with name product in edit screen backoffice

[solucionsweb]

In the backoffice product edition the name of the product disappears being replaced by a single letter, in the listing and on the web if the correct name appears, as in the database, but in the product edition no. If we store the product the name is not modified, but it is not displayed well, for example in the list appears "RASO PREMIER" and in the edition in the field name only "A".

Any solution?

Looks like it's treating a string as array. How many languages do you have?
PrestaShop version?
Did you install any back office modification?

[solucionsweb]

Currently there are 3 languages, Spanish, English and Japanese.
The prestashop version is 1.6.1.17
No, no modification has been installed in the backoffice.

Attached two captures, in the first appears the list of products with product names.

The second is the product edition with ID 1 where the name field changes

Some third party module or override might be causing it. Can you try disabling overrides from the performance options, and see if it fixes it?
