Question Bug? Light Probe Groups can't be clicked (when edit selected)

1. Click light probe group
2. Click edit light probes.
3. You should be able to click on probes ... but it just always clicks something else.

Is there a way to just exclusively see/click on the probes?

EDIT: I read that since Unity 2019, and even in Unity 2020 [still??] has a bug where you cannot click on it (how did this pass 4 iterations of 2 major betas/releases + still not fixed?). If I reset my layout for a weird workaround, it instead makes the group DISAPPEAR completely.

Even if I reload, it's just invisible. This is just so frustrating :/ 2 separate bugs entirely, both breaking.

Code (CSharp):

1. Failed opening file: 'C:/Unity Cache/GI Cache/9d/9da4565b67fd148c30c0d0e8f4175307.pos.tmp'.
2. 'Tetrahedralize Probes' job failed with error code: 3 ('Failed writing Probe Set Positions file.').

EDIT: Can't edit reflection probes either - nothing editable or interactable appears.

EDIT: This is repro'd by even a brand new scene: (1) add light probe group or reflection probe, (2) edit >> Reprod.
