Helitron results file has 0bp!

Hi there, thank you for such a great software!

I am currently using EDTA to annotate TEs in two plant genomes assembled through PacBio hifi long reads. The repeat content of the two genomes estimated from redmask (https://github.com/nextgenusfs/redmask). I give some brief details of the genomes below:

Species 1 Genome size = 3.2gb Contigs = 13,882 Repeat content = 70.%

Species 2 Genome size = 2gb Contigs = 299 Repeat content = 68%

I have opted for the divide and conquer approach using EDTA_raw.pl (version=EDTA/2.0.1) due to time constraints on my HPC. It has so far worked well for finding TIR and LTR raw TEs in Species 2 however it is struggling to find Helitrons in both. I am inclined to believe that they exist in these genomes as closely related species from the same family (Rubiaceae) have them. Essentially I am unsure whether this is due to an error in helitron scanner or the sensitivity of the search. (I have relatively simple contig headers so I don't believe that to be the problem). It seems to fill some files in the directory but others are empty (the log file and empty files in respective directories are the same in both species so I have only provided one example below) Any help would be great thanks!
