Can't create new task.

In some modules I noticed that the left section (“create new task”) does not appear. (PrtScr - https://cl.ly/2d2o3I2S1s2y).
It happens on task, workflow, target and some other modules.

I found a workaround duplicating a task and changing its content but it is not productive.

What should I do to solve it?
Already tried the quick repair.

You don’t say your SuiteCRM version, but I’m guessing you’re on 7.10.2 or 7.10.3.

If you upgrade to the latest 7.10.x that bug will be fixed.
