Can't permanently remove Lightning - it keeps coming back

Each time I start Thunderbird, I get a message telling me that Lightning 5.5b1 is not compatible with the curect version of Thunderbird and will be disabled. I have removed Lightning via the Add-ons menu many times but it comes back again. Using Thundrbird version 54.0b3 (32 bit). The system is 64 bit but I can't see that being a problem.

Is there a reason you are running beta versions? Lightning beta version compatibility chart. 5.5b1 is not listed https://developer.mozilla.org/en-US/docs/Mozilla/Calendar/Calendar_Versions
