Word strength/weakest words not quite working
I have been practising my spanish diligently the last month or so, and I can see under "words" that 80-90 % of the words have been rehearsed recently. Some words however seem not to have been practised since I learned them the first time, although i know I have in fact seen them in practice many times.
For example, looking at the word "Reyes", I am told this has not been practiced for seven months. Now I know this cannot be true, because I have written the sentence "El 5 de enero es el Día de los Reyes Magos" more times than i care to remember.
Could this perhaps be sorted somehow?
