MSG: Slice start cannot be greater than slice end

[xx3411]

Hi,
I am using loftee ((GRCh37;Ensembl API 108),and I am getting a warning for some variants related to slicing, which disables the plugin from working. Could this be related to strange input variants, or is this a potential bug?

WARNING: Plugin 'LoF' went wrong:

I have seen this issue in a previous post#31, but was unresolved.

Is there any assistance on this please?

Thanks in advance,
