Issue Wrong disk space reported

[mambus]

Hello forum. i encountered a issue in Plesk Obsidian v18.0.24_build1800200215.00 os_CentOS 7. The free disk space reported in the statistics Tab is 16 gb / 50 gb total , but in the "advanced monitoring" tab is 48 gb / 50 gb. What could be the cause of this please ? Thank you
