P: Psd file do not remember where was the last location used

Hi guys, first of all i am a french webdesigner so be kind with my english ^^
i am on a PC windows 10 the version is 1909 and all the update are done. 
My version of photoshop is the lastest 21.2.1. 

Here is my prblm : 

.psd files do not remember where was the last export
For example : i am working with 2 .psd : the "A" and the "B". I use to export the "A" works in the "A" folder and the "B" works in the "B" folder. But after the "A" exportation every others exports goes to the "A" folder. So i am constantly searching the right folder for each export. it s soooooo anoying and i am losing so much time. Do you have an issue ?

PS : i was like, f*** it i will run the odlest version i could so here i am with this cutie 20.0.9 aaaaaaaand the prblm is solved ! So from this point i will design 2019 stuff it will be so fun. But this is not an issue right ? ^^
