Adding links to buttons closes link box at first character

Hi, I’m having an issue with the GenerateBlocks button block. I can add a button, but when I go to link it to something, as soon as I type the first character in the “Paste URL or type to search” box, it closes the link box and returns focus to the button. The effect is that the first character I type in that box gets added as the “link” and the rest of the characters end up in the button. So now the link is wrong AND the button text is messed up. This is only the case when the “Paste URL…” box is empty. So if I got through that process, then click the link icon again, as long as I don’t delete the one character in the box, I can use that box to add a page link. But if I delete that character, now the box is empty and the same bug happens. (I can deal with this though it’s annoying, but when I turn the site over to my client, I cannot expect them to deal with this.)

I recorded the process which probably explains it better. The video is me trying to create a button linked the the page ‘contact’. Before I shot this I disabled every plugin except GB and GB Pro, and switched to the GeneratePress theme. Video URL in the private info.

Thanks for your time.
