english words like "sat" (past tense of to sit) automatically replaced with "Saturday"

so i switched back to English text, a few days ago, after several weeks of listening stuff in Russian and now i noticed that this app started to automatically replace normal words in the middle of a sentence with Day of the week.
the most common of these examples is the word "sat" as in the past tense of "to sit"
e.g. in a sentence like "he finished after her, who had sat there patiently waiting after her single sandwich".
the program reads me .... , who hat Saturday there patiently waiting...
every time this form of this word is used. there is no punctuation after sat to indicate it to be a shortened version -- "sat."
also the program reads all strings of numbers that are separated by a : as a time variation. "05:10" will be read as 5 hours 10 minutes, how ever in the context of the sentence it would be 5 to 10 as in a game score. but when its actually time remaining as in countdown-- "23:59:58" remaining -- it will read only part of it. 59 minutes 58 seconds and skips the hours..
 
how can i generally turn off all or some of the automatic conversions that this program does? Date/Time, Mass, Speed and some fractions?

sorry, forgot to include that information in my original post
 
i use Samsung Galaxy S7 with "Google, United Kingdom, en-GB-language". in Google TTS Options it's Voice 1. Female.
i use downloaded version, no internet connection. Intonation Expressive.
no changes of Number processing is on or off.
i have a LOT of "edits" active, however i have only 2 that have the word "sat" in it - "was sat", "were sat". both change to "was sitting" and "were sitting"

Thank you for the swift reply.
its not that i was bashing your product. i've been using it for the past several years continuously and plan to use it still even more.
its just that your response time is muuuch faster than anything from google :)
 
thanks again for your work!
