Is it normal that the BIQU Glacier plate sticks this strong?

Hi everyone,

I've been using the BIQU Glacier plate for about 1.5 months now on both my Bambu A1 and A1 Mini.

In Bambu Studio I use it as a Smooth PEI plate with 45°C first layer and 40°C for other layers, and I mostly print PLA.

My problem is that prints stick extremely strongly to the plate.

For large surface prints it's fine, because I can just flex the plate and they pop off easily. But with small surface area prints I literally have to rip them off.

If there are supports, the support first layer sticks so much that I almost have to scrape it off.

When I calibrate a new filament, Bambu Studio heats the plate to 60°C by default, and the small flow calibration rectangles are almost impossible to remove.

Even if I wait for the plate to cool down completely, the small prints are still extremely stuck.

Am I doing something wrong in the settings?

Also when the printer draws the calibration purge line, the end of the line sticks permanently to the plate like you can see in the photo, and I can't remove it.
