Note 5 Theme issues

[android_boi]

So I recently switched from a Galaxy s6 to the Note 5 and I absolutely love it. I notice an issue on the phone when I install the themes from the theme store. I noticed that there is an orange box around the "SEND" button that appears in the default messaging app but was never there on the S6. Does anyone else has this issue, if so is there a way to get rid of it. It just bothers me.
I wonder if the themes are not optimized for the note 5 yet and only on the s6 and s6 edge.

My theme doesn't have an orange box. I've had one that had a green box once.

I noticed the orange rectangle effect does not appear on the themes that the SEND button is completely rectangular. it only seems to affect the themes where the SEND button is another shape.
