Uploading Bitrix images, Importing properties?

Question

1C-Bitrix

Hello everyone, two questions.
There are links like this ftp://login:[email protected]:21/b3f0cd06-3...
The site refuses to load them, I insert the link and writes it was not possible to load
- php settings
The second question, I import the price list. There is one property (Quantity of goods in 1 m2), it is filled all right, but for some reason it does not work, and if you go to the product card and press the save or accept button, it immediately starts working
