You need to specify the resource per slot.

You need '-pe mpich 10 -l LIS2=0.10,LIS1=1'

Be careful with rounding!!!!

Eg, if you requested '-pe mpich 6 -l LIS2=0.1667' the total requirement is 6
* 0.1667 => 1.0002, and the job will not run if LIC2=1 is available.

There is an RFE for this issue, but I don't think it has been resolved.
For now, you'll have to take care of calculating the resource requirements
within a wrapper script.

Truncating after 6 digits seems to works well enough.
Here's a Perl snippet:

# resource per cpu - in-place truncation to 6 decimal places
sub rc_per_cpu {
    my $nslot = shift or return;
    for (@_) {
        /^[.\d]+$/ or next;    # only modify numerical
        $_ = sprintf "%.7f", $_ / $nslot;
        s{\.?0*$}{};           # drop trailing zeroes
