These are probably the details buttons. You need to check if access has not been blocked in Acces right > Specific Access > display specific button > Display of combo detail button

Its set to yes on my profile (Administrator).
What else could i check ?

Im not sure if its related, but i see this in the logs:

2025-04-28 08:30:52.873 ** ERROR ** [V12.1.1] [57] ERROR **

2025-04-28 08:30:52.873 ** ERROR ***** [V12.1.1] [57] cause = filemtime(): stat failed for js/dynamicCss.js

No, this does not semm to be the source of the issue.
Do you have any error in Browser console ?

The only error i see in the console is this:
failed to evaluate i18n bundle; url=../tool/i18n/nls/ro/lang.js SyntaxError: Unexpected number
at eval (eval at load (projeqtorDojo.js:2:683271), :3:345)

But i dont think i has anything to do with it, because i changed to english, and i dont get the error, and i still dont get those button on the combobox.

Can you check that you also have read access to dedicated screens.
For instance, to see buttons for field "project" you must have access rights to screen "Projects" and read access "Projects"

Im not sure where exactly u want me to check.
Also my profile is Administrator, and i have everything checked (i think).

=> Access to screen
=> Access to data

Also note that if you are allocated to a project (or parent of the projet) you'll get the profile of allocation to the project, even if you are admin : allocation can "remove" some rights.

So im not sure where exactly these options are:
=> Access to screen
=> Access to data

But, i did change the profile i had on the project, and now they appear. So that was it.
