So I merged an 80 GB unallocated disk space to my Ubuntu partition in Windows Partition software (I came from windows environment), the merge is completed successfully, but when I check my disk size in my Ubuntu using Disks, the disk size increased but the 80 GB that I just merge is somehow occupied. It says 54% full. And I only have 73 GB of free space which was my previous free space before I merge. Basically I still have the amount of free space before and after I merge my disks.
Is there any way I can fix this? My disk
