non-correct behaviour with punctuation marks on Sony XA2

Hello,

i am using a Sony XA2 with pre-installed Swiftkey. I always used this keyboard on all my devices, but on the XA2, there is a problem:

normally when you type on Swiftkey a word, you autocorrect it and then typing an punctuation mark, the punctuation mark is always behind the last word, no blank between.

But on the XA2, in some app, there is a blank between. so you always have to correct it manually, which is very annyoing.

For example, typing "trst", choosing "test" as autocorrection, followed by an exclamation mark.

standard result: test!
result on XA2 in some apps (Chrome, Tinder): test !

on other devices is dont have this problem. i also tried the beta version of Swiftkey, same problem here.

hope you can help me
