Large difference of score between odb10 and odb12

Hello,

For the same genome assembly, I run BUSCO version 5.8.3 using ascomycota_odb10 and ascomycota_odb12 and the difference is huge as you can see below:

# BUSCO version is: 5.8.3 
# The lineage dataset is: ascomycota_odb10 (Creation date: 2024-01-08, number of genomes: 365, number of BUSCOs: 1706)
# Summarized benchmarking in BUSCO notation for file FCM10-ONT-flye.fasta
# BUSCO was run in mode: euk_genome_min
# Gene predictor used: miniprot

Is there an explanation for this difference? Thank you.
