[Bug] Can't select text on Production Bento Box app on MacOS

[kr1s0404]

I downloaded the App on AppStore from my Mac.
I select Monster Craft Layout to create image, then when I try to edit the text on section "Expecto Patronum", it won't let me edit and select the text. But other sections are find and working smooth~.
