Your version of the sun-block https://www.matar.be/pwsWD/sun_c_block.php?sce=view differs from the lates June 10 version in three lines.
Line 1 uses sun_c_block.php|09|2020-12-15| although it is the June 9 version which had that 24h error.
The June 10 version removes this 24Hr problem in lines 85 and 92 and it is included in all update-files which were downloaded since June 10.
Attached a zip of that script,
Wim
@ALL Update problems after June 18, 2021 list all known problems as from June 9 and later.
