Custom field renaming - how much time/ what time the new field available in Automation rules?

Question

Hello, Community,
renaming custom field 10 AM (GMT+2), still at 6:20 PM the new field name is not available for Automation rules, just next morning 9 AM.

In workflows, on screens - updating automatically and immediately, but in Automation rules I have to replace manually (as old names appears as (deleted field?)).

QUESTION:
How much time need to get new field names?
Is there any fixed time or when field names are updated in Cloud?

Thank you in advance!

I agree with what @John Funk said exactly. Renaming a field is instant and a refreshing of you automation page should do the trick, if that field is supported.

That is very strange. What type of field is it?

Refreshing page is my most used action I suppose. :)  Does not help. 
Ok, I will check next time again.
