Hidden columns are visible again when you open the file again


Sorry for the poor english.
From version 6.3 there is a problem with hidden columns.
I have a file with data in columns A to G. I have the other columns covered. I have it in several sheets in a file. After saving the file, closing and reopening, the hidden columns are visible again. Sometimes not on all sheets.
Do you know such a problem?

How do you save your files? .ods (native format) or .xls(x) (foreign format)?

Always *.ods
