According to your log file you get seven part files with the extensions .j01, .j02, .j03, .j04, .j05, .j06, .jpa. The first six are 2000MiB big, the last one (.jpa) is 1.49GiB big.
An easy way to see that for yourself is to find the line which reads
DEBUG |20230806 19:01:21|Total size of backup archive (in bytes): 14177053908
and look at the 40 lines after it. You will see it tells you 7 files are found and lists these files as it goes through them.
Please remember that the interface always reports the total size of the backup i.e. the aggregate size of all archive part files.
Finally, please keep in mind that all Configuration page settings apply per backup profile. The log file you sent me is from profile #1 and does not have any uploading set up in it. If you have a different backup profile with uploading set up in it you will need to configure the part size for split archives in that profile as well. Select it from the main page to make it active, the page reloads, now click on the Configure button.
