I do not see the alliance's bookmarks

As an officer, if the privilege hasn't been removed by the CiC, you should see alliance markers and be able to edit them too.

Try going to 'Alliance' then 'Marker' - you should see a list of them. As an officer you should be able to add a marker (assuming there is not 10 already). You should see a list with a checkbox beside each one to indicate if it is visible to the alliance.

Something like this:

the point is that I am in an alliance and in the alliance tab is only to set up an alliance.
I do not see that I am in the alliance but I have the alliance bonus

Sometimes this failure occurs due to a problem with the "POI Manager" script.

Have you tried testing with that script turned off?

And deactivating all until finding the one that produces the failure?

Note: After deactivating an script it is necessary to reload the game to notice the changes.

Thank you very much, it helped :D
