Shoplook.io won't let me sign in when I use my computer

When I go into shoplook.io and reach the home page and then click the sign in button, the sign in pop-up comes up, but when I try to type in my email, the words disappear as soon as I write it, showing up again for a split second every time input a new character. All of which is very fine, except when I go to write the "@" part of my email, all of the characters previously inputted are deleted, effectively making it impossible for me to sign in. However, when I sign in on my phone, I'm able to type in my information without this issue. So, is this a bug that's only on computers? I have a Hewlett-Packard laptop and use Chrome. This wouldn't be a problem for me except it's almost impossible to try to design outfits on my tiny phone screen, so it would be nice if I could use my computer? I used to have a Windows tablet and used Chrome and I didn't have this issue.
