Can't click Formula/Filter/Unique tools

[OliviaL18]

I'm not able to click into any Formula, Filter, or Unique tools in any of my workflows. It's like they're read-only. I'm able to update other tools (even other Preparation tools like Select) but not these. 

Is there any setting I might've inadvertently updated that would've locked these tools like this?  

I'm using version 2020.2.3.27789. Thanks in advance for advice anyone might have.

Can you place a snapshot to show if there is any error message?

Maybe the macros are broken?

Hello @OliviaL18 ,

There was a similar issue on the 2018.2 version. Once I read your problem I thought of this:

I don't think that might be the case but anyways, better to be sure.
