Difference between IGV coverage and regions.bed
Hello,
I'm using mosdepth to visualise amplicon coverage for ONT data.
I'd to missunderstand something cause the regions.bed mosdepht give me somethings like :
```
D17763.1	311	3454	AMPLICON1	4244.00
D17763.1	2026	5000	AMPLICON2	2638.00
D17763.1	4032	6843	AMPLICON3	31887.00
D17763.1	5619	8557	AMPLICON4	0.00
D17763.1	5622	7735	AMPLICON6	25434.00
D17763.1	6252	9262	AMPLICON5	0.00
```
IGV looks like :

Why my coverage for AMPLICON4/5 is 0 instead my AMPLICON 6 are not ?

Command I used :
```
mosdepth \
    --by D17763.1.primer.bed \
    --fast-mode --use-median --thresholds 0,1,10,50,100,500 \
    Ech3 \
    Ech3.bam
```
Thanks
