totemtimers shows 2 timers on enhanced CDs frame

Hello there. I've gotten totemtimers from curseforge for 3.3.5a (TotemTimers-10.2.4).
I have an issue with displaying CDs on the buttons of enhanced CDs frame: it actually displays both timers (native one and add-on timer) at the same time. Check the link with an image https://ibb.co/L80GpcK (I couldn't find an option to attach file to the thread). Option "Hide Blizzard Timers" in global settings is on. I have used this addon in the past and don't remember such issues. Can anyone suggest what could be the problem?
