TW update: unexpected file sizes

Hi list, just did a DUP on my TW laptop (i.e., to TW20230318) and got two complaints about file size mismatches: Downloaded data exceeded the expected filesize '14.6 KiB' of 'http://download.opensuse.org/repositories/science/openSUSE_Tumbleweed/noarch...'. Downloaded data exceeded the expected filesize '151.5 KiB' of 'http://download.opensuse.org/repositories/science/openSUSE_Tumbleweed/noarch...'. Their "master"(Printrun-common-2.0.0~rc7.1599393390.c451359-24.151.x86_64.rpm) seems OK. Anyone else seen this? Cache/Mirror issue? Or something serious to report (where?)
