How many times do i need to update

Ive just noticed something when i get a request to update a plugin, I follow the instructions update plug in, then message to tell me its been successfully updated. a couple hours later or sometimes a few days later i get request to update the same plug in or a plug in i updated say the week before to the same version it repeats this for sometime ill follow instructions, successfully updating.. The past 4 days ive had request to update the same plugin ‘next gen facebook og’ 19 times about 10mins ago i updated it now its asking me to update to version i just updated to. I deactivated all the plugins still after while got same message. It’s not just the one plug in its happened to several plug ins.

anyone got any reasons why i keep having to update the same version constantly
