i'm now completely puzzled

i've entered the webmail, i removed 3 contacts and exited
then i closed the browser, cleared cache etc.
re-entered the webmail and it works correctly, the 3 contacts are gone

the tablespaces on mysql DB machine (the onet 5.1.73) are still with 2018 dates..

i've found the modifies in ibdata1 file on \mysql\data dir
is this the way mysql work?
