RFXtrx settings options missing

I am running HA version 0.116.4 and have installed RFXtrx and would like to remove unused devices. However, the Settings options - as mentioned in HA description - are not shown on my RFXtrx card? Therefore, don’t know how to remove the unavailable devices. What can I do?

This was added in 0.117, so you need to upgrade your Home Assistant.

Ok, thxs for the info. I was not sure to upgrade to 0.117, however, that’s a good reason.
