Version of ElvUI: 10.78

Did you disable all addons except the two called 'ElvUI' and 'ElvUI Config'?: yes

Did you disable all addons to make sure it is not an issue with the WoW client itself?: yes

Did you check for lua errors? (/luaerror on): yes

If you received an error then post it below (use the 'code' bbcode): no error

Please explain the issue you're having with as much detail as possible. If there is a way to reproduce the issue then mention that too.:
1. Two different profiles with different action bars configuration - position, number of buttons
2. Change profile (first time see this while changing spec)
3. Action bars change place, but have the number of button from previous profile, and highlight is in the previous place. /rl or enabling/disabling bars fix the problem.

Do you have any other information which might help us track down the issue?:
No

If your issue is graphical then please take some screenshots to illustrate it. You can attach them to your post:
Profile 1: Profile 2, wrong highlight place marked: Profile 2 after /rl:

Deferred XML Node object named PanelScrollerTemplate_v1 already exists

Please explain the issue you're having with as much detail as possible. If there is a way to reproduce the issue then mention that too.:
I use the Profiles feature of ElvUI, and have assigned different profiles to different specs for each of my characters. When I switch specs, parts of my action bars are missing completely or missing the spells assigned to them. There is no error code generated at the initial spec change. I can solve the issue by doing a /reload, but then the above error code gets generated multiple times.
