Glitch with Company Info

I am setting up my site on V9. In the Company Info section of the Configuration panel, I discovered that the default text can be edited and it will “stick” when saved, but if simply deleted that field will revert to the default.

Example: I changed my company name, email and ceo name, but I do not want my address, fax or phone number displayed so I deleted the default text then saved. However the address, fax and phone reverted to the defaults. I then entered “0” in each of these fields before saving and that did the trick. So it seems these fields are not permitted to be left blank.

Only a minor issue, but wanted to bring it to your attention.
