Disk Space changed from 128M to 16M

Hello,

I have 3 Mikrotik Routerboard 750 R2.
Before update firmware of them, It has 128M Disk space and 80% Free, But After upgrade two of them, It changed to 16M and 18% Free, Why ?!!
Please See the attached photo.

RB750 R2 is supposed to have 16MB flash.
Can you please post what you get in System → Resources on both routers (the one affected, and the one that is not).

Nothing has changed, RB750r2 only has 16MB storage

Please see the attachments,
Disk space on RTR01 and RTR02 after update changed to 16M
But RTR03 has 128M disk space still and I’m sure after update it will change to 16M too

Well, RB750 (first screenshot), RB750Gr2 (second screenshot) and RB750r2 (third screenshot) are three different models with distinct specs. The RB750Gr2 and RB750r2 have always had only 16MB available.

Thanks
