RedirectTo, AmpScript and website-generated parameters

Question

I have a URL that is created with some Ampscript that needs to have click-tracking. However, there are parameters that our 3rd party's website adds and I believe that is breaking the link.

Here's the AmpScript I'm using to create the URL:

%%[
    var @Store_Id, @Store_Link, @RSTR_PLRS_First_Name, @SN_TMS_Name 
    SET @Store_Id = SL_Store_Id
    SET @Store_Link = Concat('https://teamlocker.squadlocker.com/#/lockers/', @Store_Id)
]%%

<a href="%%=RedirectTo(@store_link)=%%">Link</a>

So, when I go to test the link - this is what it's generating:
https://teamlocker.squadlocker.com/#/lockers/49753?cm_ven=ExactTarget&cm_cat=SE_SquadLockerTeamStore_Parent_Email1_jordan&cm_pla=All+Subscribers&cm_ite=STATIC+TEXT+HERE&[email protected]&cm_ainfo=&&&&%%__AdditionalEmailAttribute4%%&%%__AdditionalEmailAttribute5%%&_k=h94gl3

The final parameter &_k=h94gl3 is generated from the webpage.
The webpage should render like this: https://teamlocker.squadlocker.com/#/lockers/49753?_k=h94gl3

If the &%%_AdditionalEmailAttributeX%% breaks your links, you could raise a support case via the Help & Training Portal to enable all available additional email attributes. Then you can set them in the properties of your emails. For every unset parameter just an ampersand is added to the url which shouldn't break the link. The other automatically added parameters like cm_ven, cm_cat, etc. shouldn't break your link either. You could also add an alias to your link, so this is set as cm_ite value.
