Level bug?

You stay in already entered giveaways, so you still have chance to win them. ;)

A little sample of the FAQ:

Why did my level decrease?
There are two reasons why a decrease could occur.

• Values are calculated based on the current USD prices of games in the Steam store. If a game lowers in price, the value of previously created giveaways will adjust accordingly, and this will be reflected on profiles and levels.
• Certain games on our site are flagged as "No Value" or "Reduced Value". This is done manually by our volunteers, and therefore there might be a delay before these values are assigned. For example, a game might be included in a bundle on January 10, 2018. If on January 13, 2018 we flag that game as "Reduced Value", with an effective date starting January 10, 2018 (the day the bundle started), then giveaways created between January 10-13, 2018 would have their value reduced accordingly.

When something gets into bundle list, it stays there.

It won't go back up. Just recently Crusader Kings II went F2P so all those give-a-ways went to 0 value, and many lost CV. That's just the way the site works.

This is the value you were supposed to get in the first place, it's just that nobody knows in advance whether bundles like Humble Monthlies will hit the treshold for the bundle list (around 95% discount), so they're usually left alone at first, and eventually added to the list once they're revealed, if needed. This is permanent.

In general, with Humble Monthlies, you should never expect to gain full unbundled CV, since the bundling treshold is quite low at $216+ total MSRP (sometimes even lower, depending on active promotions)

If you only gift bundle stuff don't expect to become level 4 with just a few games, especially not level 7-8, expect to spend $1000+
