RB951-2HnD blocked some features ...

Home was purchased, configured, and forgotten.
Purchased a month later, approximately, after release (the first batch probably).

I decided to upgrade to 6.4 and found that almost all the functionality is not available (in a gray Winbox’e).
Updated easily. But was able to reconfigure the only 2 times. In the first part of the functionality is blocked on the “half-way”. The second time, all through the terminal - working.
The device works, the console is available, you can update, etc.
Now part of the functionality is not available - see the attached file a screenshot, after updating.

At work, such 3 (bought later) did not notice anything like that. In addition, there are a couple of 750GL - with them all too well.

Who knows what kind of trouble?

The disabled options is a known problem with RouterOS 6.4. If you close the option window and reopen it, the options should be re-enabled. Or you can downgrade to 6.3.
