A pool can’t “boot you off” even if they are oversubscribed (over-saturated).
The good news here is that you did not loose your delegation and you really don’t have to do anything.
The not so great news, is that this is a user interface bug in Daedalus and should get corrected today/tomorrow. Daedalus has a bug where it’s not correctly showing all pools and sometimes at random.
Again, your ADA remains delegated correctly and you don’t have to do anything. This will sort itself out on the UI with the new release.
With that said, sometimes this happens because pools are changing parameters. For example some pools “promised” a very high pledge amount to attract delegators and now that they have them, they are changing their parameters (which is allowed) and going down to a very low pledge, or increasing their fees. This requires them to update their metadata and that likely has “tickled” this bug for you on these pools. I am not saying that is the case here, but please do be aware of this. You can check the latest fees/pledge for the pools you delegated to on pooltool.io or adapools.org
Finally, please consider staking with us at CPX
We have good pledge and a great fee structure that we know we can sustain for years to come, i.e, we won’t change it!
Hope this helps.
