The replacement dialog always displays the dialog.
Even if you use the option to hide this dialog, it will always be displayed when you reopen it.
This is a temporary setting until the file is closed.
This makes no sense for options. This dialog is very disturbing.
Steps to Reproduce:
Open the replacement window.
Search and replace something.
Check Search dialog > show this dialog disable
Check Replace dialog > show this dialog disable
File save, close calc
Open calc again
Do the same, the dialog will always be displayed.
User Profile Reset: Yes
You need an option to not always display the dialog, not a temporary setting.
This is better position > Tools> Settings> calc.
You already have this in 6.3: Tools - Options - Calc - View: Window - Summary on search
