Is this a glitch?

[Uhx]

To begin, let me say I'm a new player on this game, still leveling my sin. 

 

This is the issue I have : so when I was at lower levels, I noticed that after I successful used decoy or blink stepped or tab+infiltrate  and started to do the usual LMB + F cancel (with the proper SP) my sin, out of nowhere, kicked my enemy, kncking it down and also putting me out of stealth. I really don't know what caused my char to do that, since I wasnt pressing any other skills buttons besides spamming lmb and f. 

 

After a while, my sin stopped to do that. Like really, I didnt change anything on my method or SP.

 

And now its back. I have no idea of what this is. 

Can anyone help me?

maybe u used SS , or tab or something , i think you triggered , the F that kick down , by smashing F/LMB (isn't is RMB ? :o )
