zram-config throwing some errors on boot

I noticed that zram-config throw some errors on boot (after checking logs). Here are some examples:

kernel: zram: Cannot change disksize for initialized device
init-zram-swapping[1039]: /usr/bin/init-zram-swapping: 21: echo: echo: I/O error
init-zram-swapping[1109]: mkswap: error: /dev/zram0 is mounted; will not make swapspace
init-zram-swapping[1124]: swapon: /dev/zram0: swapon failed: Device or resource busy

systemd[1]: zram-config.service: Main process exited, code=exited, status=255/EXCEPTION
systemd[1]: zram-config.service: Failed with result 'exit-code'.
systemd[1]: Failed to start Initializes zram swaping.

I saw some old bugs similar to this, but none opened at this moment. I'm not sure how to proceed before starting any bug report. Thanks!
