Sent bitcoins and electrum signed and verified like normal.  Transaction shows under history and unconfirmed status at the bottom.  Problem is the transaction never got broadcast to the blockchain.

I tried updating to lastest client 2.6.4 and restarting program but blockchain shows nothing.  Any ideas?  I am connected I see the green dot on bottom right. 

2 days ago I sent bitcoins from electrum version 2.5.4, but I didn't include a large enough fee so it sat unconfirmed both in electrum and on blockchain.  I learned my lesson there    

After about 24 hours when I opened electrum the bitcoins reappeared in my wallet and the transaction was removed from history.    

What's confusing is I checked blockchain.info the transaction was and is still showing unconfirmed.  So I switched to another electrum server on a whim, and after syncing, the transaction reappeared and the bitcoins were gone from my balance and showing as unconfirmed again in electrum.  

Why does the server I used to send show bitcoins returned to my wallet but other servers that I didn't use to send show bitcoins as missing and unconfirmed?  
Why didn't the blockchain remove the transaction?
And have the bitcoins been returned and I can send them again to same or different bitcoin address?
