Regular words being replaced with (learned) capitalized version

[kaoneko]

Describe the bug
Since switching to com.leanbitlab.leantype.offline and version 4.1.8, whenever I write a regular word capitalized (i.e. at the beginning of a sentence), it is then (after $learning_threshold times) learned and subsequent swiping of the word results in it being written Capitalized everywhere.

I have Add learnt words to personal dictionary enabled, so I can see all those capitalized variants of regular words being added to the dictionary.

To Reproduce
With the default learning threshold of 2 times, you could try to swipe:

Keyboard test. Keyboard test. Just testing the keyboard.

The last keyboard will come out capitalized, as Keyboard is now a learnt word.

Expected behavior
Not this.

Screenshots
Not needed.

App version & Flavor
com.leanbitlab.leantype.offline 4.1.8

Device Info

• Model: Motorola Edge 70
• OS version: Android 16

Still happens in 4.2.0:

Keyboard test. Keyboard test. This is a Keyboard test.

Gets added back to the personal dictionary every time after removing it. But I discovered that the issue doesn't occur when disabling Add learnt words to personal dictionary, so I'll leave that off for now.

the add to personal dictionary boost the weight of the words than the dict words so its working as per design for user who prefer personal suggestions than the main dict , that's the reason i added more suggestion customisation like the the slider to be more personalized or more accurate as per main dict

I'm thinking maybe you misunderstood the issue. The issue is that regular words that are already in the language dictionary—like it, the, why, when are "learned" as if they were new words when written with an uppercase first letter. This shouldn't happen, and didn't before v4.1.8. LeanType shouldn't think of them as new words when they aren't. Lots of words will sometimes be used capitalized at the start of a sentence and other times all lower case mid-sentence.

Otherwise, maybe I'm misunderstanding the Add to personal dictionary setting 🤔

hmm, ill check deep, something is wrong around the suggestion logic
