[BUG] memory not showing

[sterculius]

first i installed bashtop with apt install bashtop , everything works fine, except the memory part, then i read the installation guide, purged the apt install i had and manually installed it, and im with the same issue, there is nothing on error.log except loggin the new instances of bashtop.
isnt a mem error on my machine because htop,top,gotop works fine and shows the correct ammount of used mem,free,etc.
i probably will try to fix this later when i have some time idk

my uname -a:
Linux debian 4.19.0-13-amd64 #1 SMP Debian 4.19.160-2 (2020-11-28) x86_64 GNU/Linux
