How to see relavent error of the arrow

Sometimes when I click on an Error arrow, it shows me the Error details and some times it just tells me that the thing I clicked on is an Error arrow. How do I make it do the first thing and not the second.

Your category is layout so I assume you are discussing DRC and not ERC?

Kicad 9.99 is the unstable development program that is altered on a daily basis. Faults and problems come and go on regular basis.
The best solution is to wait a few days, download the latest version, and if the problem persists, file a bug report. Any Kicad X.99 should not be used for serious design work.
Take not of this warning: https://www.kicad.org/help/nightlies-and-rcs/

And to add to what jmk said . . . any files you save in V10 (9.99 nightlies) usually won’t be able to be opened in the currently released version v9.0.0

OK, anyway, the problem is not related to version. Kicad 8 does the same thing for me. Sometime it just tell me what I clicked on is an arrow and sometimes it take me to the specific errors in the list of errors.

Can you upload a copy of your Project, I can’t replicate that behaviour on V8.0.8 ?

Sorry, its proprietary. But I can post a screenshot.

Maybe the issue is primarily with this old user of Kicad. I mean when I click on an error arrow, I’d gotten used to it going to the DRC list and showing me the error details there , but it tells me a little of what I need to know this way also. Maybe its supposed to work that way.

Look at the message panel:

Either you are holding the mouse button too long and doing a “Long” click . . . or; there are two markers at the same position so KiCad doesn’t know which one you want info on.

Just click the one you want the info about and it should be highlighted in the Design Rules Checker window.
