I had the same issue. I was going to start a print with a spool of ABS that was nearly out and have it switch to the full spool afterwards, but instead it printed the whole thing with the full spool. Thankfully not a big deal as I have a couple more of this item to print out, but it is concerning that its not using the correct slot I ordered in the studio. I think I also had the issue doing a reprint from my phone, same type of issue. I’m willing to bet its something to do with the cloud service goofing something up
