rebuild object : storage clause adjustment : remembers setting of extent size but now it is unset

In the window “Rebuild multiple Objects” i have set the extent size in the storage clause adjustment.

In the next step i had unset the chapter "change extent sizes to the following.

But in the next “rebuild” execution i find the objects rebuilded with the setting before,

althoug it is now unset.

There are Save/Load buttons on the toolbar above any of the settings related tabs which will save/load all settings to a file. Use those to remember your settings.
