http://prntscr.com/e76knlThe electrum client still thinks that you want to send your transactions manually. Restart your computer and try it again (after shutting down the electrum wallet - unless you've already done this since changing the preferency settings).
IF you hover over part of the pointer, does it give a percentage - if it does, move the slider up to 100%.
Also, you can use this acceleration I think with your transactions:
