PA6-GF leaving raised glue on Engineering plate

Printed with the new PA6-GF on the Engineering plate and it left a raised imprint of the model pieces, like it cooked the glue in the shape of each piece. Bambu recommends glue stick when using PA, and I used the default profile for PA6-GF in the latest Beta slicer. The bed was scrubbed prior with warm water and Dawn soap. Then I applied the Bambu glue stick. After the print I washed the build plate and the raised areas would not come off. Is the plate ruined? I tried soaking it in warm water and Dawn dish soap for 30 minutes, but it didn’t help.
