Problem to control my ac Sanyo with Broadlink RM4 mini

Hello everyone, there is something strange with my Broadlink RM4 mini. I have a Sanyo air conditionner that works correctly with its remote control, i installed the broadlink app and choosed a brand. Every mode works, the thing is i have to press several times and quickly on a button control, for exemple ON , to have a response…

If anybody can help me with this it will be great,

Thanks in advance.
