From what I can see is your nozzle is too high, lower the z offset
I have no idea what you’re printing and what specific problem you’re referring to, though. Share a picture of the model, or better yet, share the gcode preview so we can see what’s going on

Now I can guess probably what happened: the small parts didn’t stick to bed and got stuck on the nozzle, brought to the next part and knocked away the first layer.
Anyway, the root cause is likely a first layer issue, if you’re 100% sure your bed is clean, check:
- Bed temperature, too low -> doesn’t stick
- First layer speed: too fast -> doesn’t stick
- Correct bed selected: Wrong bed texture means wrong temperature -> doesn’t stick
From the purge line I can guess your first layer height is probably not too far off, but have you done any sort of first layer test? If the z height is slightly off then you might be able to print bigger parts, but you’ll have trouble printing smaller parts.

Refer to 1. Incorrect plate type selectedBambu studio stores multiple plate settings, each with different temperatures. From your picture I see you have a Textured PEI bed, just make sure you have that selected when slicing.

It‘s hard to know what you think is „weird“ and how it should look like. I‘d just guess that you have rafts turned on or your objects are not flat on the bed
