It says "2fa".
How come they aren't SegWit ?
Because Electrum "2FA" wallets do not use SegWit... they are simply a type of MultiSignature (aka "MultiSig") wallet... that utilises the services of TrustedCoin's Google Authenticator system to provide Two Factor Authentication security for your wallet.
Just because *some* "3"-type addresses are SegWit... does not mean ALL "3"-type addresses are SegWit addresses... It is impossible to tell what type of address a "3"-type address is, unless you know it's redeemscript.
What will happen to the Bitcoin I stored to my Electrum wallet can I withdraw it later if they already fix it or I have to withdraw it and shut down my Electrum wallet?
Already fix what? Are you asking about the "bug" that was recently discovered? If so, go start a thread of your own instead of hijacking a completely unrelated thread
But to answer your question, the bug is an issue with the application... NOT the wallet file or format. If you upgrade to the latest version and have a wallet password set, your wallet is relatively safe.
