It doesn't appear on blockexplorers as the transactions that you've created with Electrum conflicts with the two transactions above, for which neither signals opt-in RBF. The Electrum node that you were using most likely already dropped the transaction, given that the minimummempoolfee is currently bigger than 5 satoshis by default implementation. Blockexplorers might not be able to see it but it's fine as long as nodes are willing to relay it; not a big issue and nothing much that you can do at this point anyways, other than moving away from Blockchain.com.
These transactions you showing me are from March 5, it is not what I sent today.
