Problem with recently used blocks

I have a problem with the last used blocks

The problem with me is that when I use the Twitter block, or the Delimiter tool, for example, the last blocks or tools I use don’t show up in the six items shown (as you can see in the picture). And because of this I have to constantly type in the search engine the name of the specific tool when I want to use it.
I apologize for my poor English.
