Custom field showing up even though empty

-- HikaShop version -- : 4.4.5 Business
-- Joomla version -- : 3.9.10
-- PHP version -- : 8.0.14

A custom field called MSDS (next to Specs and Broschure) is all of a sudden showing up all the time even though there is no value associated to the field.
This only started to happen, it has been in place since a long time and was working fine before updating to the latest versions.

Do you have any suggestions? Thank you.

Hi,

There must be something wrong in the code of the view file show_block_custom_main.php on your end.
I can see it has been heavily customized so you might have old code in there which isn't matching with the new code of the rest of HikaShop.
I would recommend editing that view file via the menu Display>Views to check what is in there.
