I feel like an idiot Parasite Clear Tank Buddies, Jungle

So, I have a ten gallon tank and my gold fish in there has anchor
worms. I bought these fizzy tablets (Parasite Clear Tank Buddies by
Jungle) and for the life of me, I cannot understand the directions.
Here they a

"Remove carbon filter during use. Add one tablet to each ten US gallons
of Aquarium water. Treatment may be repeated up to two times with 48
hours between treatments and a 25% water change. For anchor worms and
fish lice, repeat treamtent three times, using once a week with a 25%
water change. "

Yeah, maybe it is just me, but I was confused how often I should use it
for my anchor worms. So I went onto Jungles website to see if I would
have better luck. They say;

"Wait 48 hours between treatments. Remove activated carbon. Change 25%
of the water before each new treatment. For anchor worms, repeat
treatment up to three times, once a week, for three weeks. For fish
lice, treat once a week for three to five weeks. DO NOT OVERDOSE.
Active ingredients: praziquantel; N-[[(N-Chlorophenyl)amino]carbon
1]-2,6-difluorobenzamide; metronidazole; acriflavine."

Now, do I put three tablets in a day? Or do I put a tablet in every
48hrs for three days? Do I put a tablet in every week for three weeks?

I think that I put in three tablets once a week for three weeks, but
how long should I wait between tablets?

If someone could explain this to me without making me feel like that
much more of an idiot i would be very grateful.
Thanks
