Problem Issue modification / upgrade price product on HIKASHOP 3.0.1

Hi Togheter, I have one problem in The Hikashop version is (3.0.1). This problem occurs when I update/modify the product price by clicking on (ok Hika) and then Save. (Can't save the change, It only happens if I change the price and save it). (And this symbol appears in the url bar #)
Other product changes save you.
How can i solve this problem?
Mozilla Firefox, 53.0.1
Thanks.
