I'd previously renamed a block parameter variable from text to val which visually worked fine but I got this little glitch when I tried duplicating the block
Could just be a one-off but mentioning it in case not
I’ve had similar experiences (though I can’t reproduce those cases right now)
It won’t happen if you use rename all …, if applicable.
I used rename all.
I can't replicate so it's no biggy
I'm 100% sure, definitely has happened to me.
