Tiny blue box in text bubble

I have a galaxy s7 edge and over the past few months when texting a tiny blue rectangle pops up (randomly) after my text in the conversation bubble. It looks like it says a word but only a very small piece of it shows up. This doesnt happen on all of my texts, just randomly here and there. I tried to Google it but cant find anything about it. Help!! Im wondering if my phone is hacked or if some sort of spyware may be the cause.
