Why is it ?

Have a question for someone? The other day i wiped my firestick clean…… Because i wanted to update it…. I have two firestick bought same time and same place…… I went to kodi download page and download the Kodi 17.0-RC1 > ARMv7a (32bit) <<< file,, Installed it, and played with it for a few days…. BTW love the new look and feel of it…. Back to the story….. So i complete my first one and it is running great,,, So wanted to update the second one,,, Did the same as the first step by step…. Went to Kodi Download page threw es explorer,,,, went to ARMv7a (32bit) <<<<< Downloaded ok ,, Went to install the same file i used on the first one,, and all of a sudden,,,,,, open it up and it said 17.0 Beta ? this threw me for a loop,, Plus when installing at the end,, a warning came up saying there is a newer release for 17 > RC3 , so i thought i did something wrong and started again, Same thing download ARMv7a 32bit, installed and it installed the same 17 beta,,,, Can some kind help me out on this one??
