Changing membership levels

Really like your plugin. It works almost perfectly for our site (www.gcelfun.org)

One thing we’ve noticed in the debug log is that when a member pays their membership fee, regardless of the level they pay for (we have several levels of payment) – they are defaulted to the basic membership level (in our site, that is level 3). Anyway to have, at a minimum, members retain the level they have before they pay their membership fees?

See debug log below:
