Most icons missing from control/fu​nctions palette

Question

I've seen the following on several (at least three, AFAIR) different installations of LV8.5 or 8.5.1 on different machines. I'm surprised not to find something that inconvenient not yet reported on the discussion forums or the knowledge base.
If in Tools/Options/Control/functions palette I choose "Icons" for format, which I like best, I end up with a control palette showing only 4 buttons, namely Express, User controls, Select a control... and Vision, and a lot of blank space. Similarly, the Controls palette shows only Express, Favorites, Select a vi... and User libraries. If I use format:tree or format:text, I see the same four items as well. The tagging of "load palettes" doesn't seem to have any effect on this.
Instead, all the functions and controls I expect to see, are on the system and show up in submenus only if I choose format: category. However, and this might be the key point, the category menu is shown initially as "abridged", with a >> mark at bottom. As I right-click pop it open, only the said four items are shown, a click on the continuation mark opens up all. I couldn't find, though, any obvious Options setting related to this behavior.
I've checked this resource,

but none of the suggestions seems to apply. I have not tried to reinstall LV, first for the time it takes, second because having seen the problem on many installations I doubt that all of them could have gone bad in the same way (while LV apparently works sanely). In particular, Tools/Advanced/Edit palettes shows again all buttons I would expect to see.
What should I do?
Thanks, Enrico

Uff, I found myself. Please ignore the request.
However, I find that it was not at all trivial. Searching the help for "abridged", I've found that:
"By default, LabVIEW installs with an abridged palette view, unless you are upgrading and were using the Advanced palette view in a previous version of LabVIEW. You can use the View button to display or hide palette categories."
(upgrading was the case on the systems in question). Following links for "Change Visible Categories Dialog Box" I learned that
"On a pinned palette, click the View button on the palette toolbar and select Change Visible Categories from the shortcut menu to display the Change Visible Categories dialog box. This dialog box lists all categories on the Controls or Functions palette"
That is, one has to pin the palette first, then press view, then etc. etc. It was not immediate to me.
