Might be a weird question or already answered but I created a standard wallet with segwit adresses (those starting with bc1) with Electrum 3.1.3.

Have Electrum 2.8.something on an old PC (think it's 2.8.1). Tried to restore the standard wallet with segwit addresses created with 3.1.3 from seed with Electrum 2.8.x and it won't recognize the seed. Checked multiple times, copy and pasted. No go. Is this because segwit adresses were only implemented with 3.0?

Also weird bug, when I type the seed of the wallet created with 3.1.3 to restore with 2.8.x at word 6 and half (!) of the seed suddenly the next button gets grey. When I click it it tells me I can restore a wallet with 2Fa now. When I click on this I get an error window with the possibility to send a bug report?

Thanks in advance.
