Lookup Dictionary

This is a response from iOS saying it can't find the selection, "merisms" listed in the iOS dictionaries you have installed on your phone so you should try installing a different available dictionary (IOS SETTINGS->GENERAL->DICTIONARIES).

I have had this happen from time to time and overcome it by reselecting the word without the "s" selected, so in this instance select only "merism", and then a result is found. However I just tried it in this instance and just selecting "merism" and no result was found.

So in these instances where a result can not be found in one of the system dictionaries, I move on from the Lookup command and choose the search option, a little bit less inconvenient as it opens a new window but it brings up search results and the definition of the word I'm looking is then found. In this case Logos Search can handle the term "merisms" and returns dictionary entries for "merism".

When I click on a word to get its dictionary definition the lookup popup gives me an error message stating that I don’t have a dictionary loaded. (See image)  I checked for loaded dictionaries and there are 2, New Oxford and Apple dictionaries Installed on my device. 
I am using an iPad Air with iOS 14.5.1 and I performed a reboot. Nothing changed. I am using Logos 9.

Help would be appreciated!
