Galileo F/NAV not read if both F/NAV and I/NAV present?

Hello,
I am using georinex to read mixed navigation files. The file has 31 ephemeris for Galileo E03, for all epochs there are both F/NAV and I/NAV message and these have different SISA. However, georinex does not read the FNAV message properly (or at all) because if you check the file for E03 and then what georinex reads, there should be also -1. values here:
E03:
<xarray.DataArray 'SISA' (time: 48)>
array([ nan, nan, nan, nan, nan, nan, nan, nan, 3.12, 3.12, 3.12,
nan, nan, nan, nan, nan, nan, nan, 3.12, nan, nan, nan,
nan, nan, 3.12, 3.12, 3.12, 3.12, 3.12, 3.12, 3.12, 3.12, nan,
nan, nan, nan, nan, 3.12, 3.12, 3.12, nan, nan, nan, nan,
nan, nan, nan, nan])
Coordinates:
sv <U5 'E03'
* time (time) datetime64[ns] 2022-05-30T23:30:00 ... 2022-05-31T07:30:00
This plot should have 31 points but there is only 15.
Attached are two example files that both show the same behavior.
