CPS tag not working when using with glitch effect

[Cyber-Tokyo]

I am trying to change the text speed for the text. I set up my defined variable in options.rpy, but when using the {glitch} tag, the text shows immediately instead of displaying the text as per the cps speed. I also tried using the cps tag, but still shows the text immediately. Any ideas?

Here's how I'm also adding the cps tag to the glitch effect

Eileen "{glitch=25.0}{cps=25}This is my typewriter text hehe{/cps}{/glitch}"
