Last error in WEBUI, when no error happened

[EmilioMoreno]

Describe the bug

Web Interface "Last Error" showing error timestamp, but job execution list shows no error
We have a job every 15 minutes which failed several times about 3 days ago. The last error field and the specific job execution list are a match.

Today without any error on the job execution list, the "Last Error" field on the Jobs section at the WEBUI has been updated, several times during the day, but always the execution list is clear. No failures shown, no retries, nothing, all the executions for that job are showing a check.

To Reproduce
Steps to reproduce the behavior:
Sorry, no clear steps to reproduce

Expected behavior
If the job section show a Last Error timestamp, the corresponding execution in the execution list should be in error at that date

Screenshots

** Specifications:**
Agents and servers running linux, 3.2.7
5 servers, 4 agents available for this specific job.

Additional context
The job at that time was indeed finished without any error
